42 is a multiple of these numbers: 1, 2, 3, 6, 7, 14, and 21 because 42 divides evenly by each one with zero remainder.
Is 42 a multiple of 3 yes or no?
Yes, 42 is a multiple of 3—just multiply 3 by 14 to get 42, no leftovers.
Want a quick check? Add the digits: 4 + 2 = 6, and 6 is clearly divisible by 3. Or just scan the multiples of 3 until you hit 42: 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36, 39, 42… there it is.
Which number is 42 a multiple of?
42 is a multiple of 1, 2, 3, 6, 7, 14, and 21—those are the only whole numbers that fit evenly into 42.
Run a quick division test: 42 ÷ 1 = 42, 42 ÷ 2 = 21, 42 ÷ 3 = 14, and so on. Every result is a whole number, so those are your factors. Handy for trimming fractions or cracking algebra problems.
Is 42 a multiple of 4 yes or no?
No, 42 is not a multiple of 4—divide 42 by 4 and you get 10.5, which isn’t a clean whole number.
List the multiples of 4 and you’ll see: 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44… no 42 in sight. Another fast trick: if the last two digits of a number don’t divide evenly by 4, the whole thing fails the test. 42 flunks that check.
Is 42 a factor or multiple of 14?
42 is a multiple of 14—just multiply 14 by 3 and you land exactly on 42.
Flip it around and you’ll see 14 is a factor of 42. Picture 14 cookies. Group them into sets of 3, and suddenly you’ve got 42 cookies. So 42 is literally built by stacking 14 three times.
What are the 10 multiples of 42?
The first 10 multiples of 42 are: 42, 84, 126, 168, 210, 252, 294, 336, 378, and 420.
Multiply 42 by 1, 2, 3, all the way to 10 and you’ll get that list. These numbers are the foundation for spotting common multiples and cracking divisibility puzzles.
What are the factors of 42 in pairs?
The factor pairs of 42 are: (1, 42), (2, 21), (3, 14), and (6, 7).
Start with 1 × 42, then 2 × 21, and keep going until the pairs meet in the middle. These pairs break 42 into simpler chunks, which comes in handy in algebra and number theory.
What does it mean to be a multiple of 3?
Being a multiple of 3 means the number can be written as 3 × n, where n is a positive whole number.
Take 9: 3 × 3 = 9, so it’s a multiple. You can also add the digits—if the total is divisible by 3, the number itself is a multiple. This trick pops up everywhere from divisibility rules to modular arithmetic.
What are common multiples of 3 and 9?
The common multiples of 3 and 9 are 9, 18, 27, 36, 45, and so on.
Since 9 is already a multiple of 3 (3 × 3 = 9), every multiple of 9 is automatically a multiple of 3. The smallest of these is the least common multiple (LCM), which is 9 here. Listing them out helps with timing problems and shared intervals.
What is the smallest multiple of 7?
The smallest multiple of 7 is 7 itself (7 × 1 = 7).
That’s the starting point of the sequence: 7, 14, 21, 28… Any number times 1 is itself, so 7 is the base. This idea shows up in weeks, geometric patterns, and more.
Is 20 a multiple of 3 yes or no?
No, 20 is not a multiple of 3—divide 20 by 3 and you get about 6.666, which isn’t a whole number.
Scan the multiples of 3: 3, 6, 9, 12, 15, 18, 21… no 20. Or add the digits: 2 + 0 = 2, and 2 isn’t divisible by 3. Quick mental math like this keeps you from making silly calculation mistakes.
What are the first 5 multiples of 8?
The first 5 multiples of 8 are: 8, 16, 24, 32, and 40.
Multiply 8 by 1 through 5 and you’ll get that list. These numbers show up in work shifts, measurements, music beats, and even byte sizes in computing.
What are the first 3 common multiples of 3, 4, and 6?
The first three common multiples of 3, 4, and 6 are: 12, 24, and 36.
List the multiples of each: 3 (3, 6, 9, 12…), 4 (4, 8, 12…), and 6 (6, 12…). The numbers that appear in all three lists are your common multiples. The smallest one is the least common multiple (LCM), which is 12 here. Super useful for scheduling and sync problems.
What is the HCF of 46 and 8?
The highest common factor (HCF) of 46 and 8 is 2.
List the factors of each: 46 has 1, 2, 23, 46; 8 has 1, 2, 4, 8. The biggest number in both lists is 2. This comes in handy for simplifying fractions and working with ratios.
What can be multiplied to get 14?
You can multiply 1 × 14, 2 × 7, 7 × 2, or 14 × 1 to get 14.
Those are the only whole-number pairs that multiply to 14, so 14 is a composite number, not prime. Knowing these pairs makes breaking down numbers easier in calculations and equations.
What is the LCM of 30 and 42?
The least common multiple (LCM) of 30 and 42 is 210.
Break it down with prime factors: 30 = 2 × 3 × 5, and 42 = 2 × 3 × 7. The LCM takes the highest power of each prime: 2 × 3 × 5 × 7 = 210. This is the magic number when adding fractions with different denominators or hunting for repeating cycles.
What are common multiples of 3 9?
9, 18, 27, 36, 45, and so on are the common multiples of 3 and 9.
Since 9 is 3 × 3, every multiple of 9 is automatically a multiple of 3. The smallest one is the least common multiple (LCM), which is 9 here.
What are the first 3 common multiples of 3 4 and 6?
12, 24, and 36 are the first three common multiples of 3, 4, and 6.
The multiples of 3 start 3, 6, 9, 12…; 4 starts 4, 8, 12…; 6 starts 6, 12… The numbers that show up in all three lists are your common multiples. The smallest is the LCM, which is 12.
What is the LCM of 30 42?
210 is the least common multiple of 30 and 42.
