There are only 12 positive numbers that can add up to 12 though. (0+12), (1+11), (2+10), (3+9), (4+8), (5+7), and (6+6). I hope this helped, and if you have any further questions, feel free to ask.
The factors of 99 are 1, 3, 9, 11, 33, and 99 .
The trick is realizing that 1 + 100 is 101, as is 2 + 99 and 3 + 98 and so on, through 50 + 51. That’s 50 pairs of numbers that each add up to 101. So the answer is 50 × 101. That’s 5,050 .
The number of combinations that are possible with 20 numbers is 1,048,575 .
The number of combinations that are possible with 7 numbers is 127 .
Two prime numbers that add up to 40 are 3 and 37 , but they also can be 11 and 29 as well as 17 and 23.
40 is a composite number. 40 = 1 x 40, 2 x 20, 4 x 10, or 5 x 8. Factors of 40: 1, 2, 4, 5, 8, 10, 20, 40. Prime factorization: 40 = 2 x 2 x 2 x 5 , which can also be written 23 x 5.
The sum of all natural numbers from 1 to 100 is 5050 .
Between 1 and 40 prime numbers are 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37 .
The first five multiples of 8 are 8, 16, 24, 32, and 40.
When we list them out like this it’s easy to see that the numbers which 40 is divisible by are 1, 2, 4, 5, 8, 10, 20, and 40 .
The GCF of 40 and 48 is 8 . To calculate the GCF (Greatest Common Factor) of 40 and 48, we need to factor each number (factors of 40 = 1, 2, 4, 5, 8, 10, 20, 40; factors of 48 = 1, 2, 3, 4, 6, 8, 12, 16, 24, 48) and choose the greatest factor that exactly divides both 40 and 48, i.e., 8.

Similarly, 12 lies between 9 and 16 so √12 lies between 3 and 4.
There are two numbers whose sum is equal to the difference of their squares , and if the sum of the squares of the two numbers be subtracted from the square of their sum, the remainder will be 60.
0, 15, 16, 76, and 110, etc. all are examples of whole numbers.
The first ten multiples of 3 are listed below: 3, 6, 9, 12, 15, 18, 21, 24, 27, 30 .
The first five prime numbers: 2, 3, 5, 7 and 11 . A prime number is an integer, or whole number, that has only two factors — 1 and itself. Put another way, a prime number can be divided evenly only by 1 and by itself.
2 + 99 = 101 . 3 + 98 = 101. . . . 50 + 51 = 101.
3+97 and so on. Only 50 and 100 are left out, so the remaining 98 numbers can be paired to get a sum of 100.
And hence the sum of the first 50 natural numbers to be 1275 .
There’s (45 x 44 x 43 x 42 x 41 x 40) / (6 x 5 x 4 x 3 x 2 x 1) combinations. And that simplifies to 8,145,060 combinations .
So for 8 people there are 8! 4! 24= 105 possible sets of pairs.
There’s (45 x 44 x 43 x 42 x 41 x 40) / (6 x 5 x 4 x 3 x 2 x 1) combinations. And that simplifies to 8,145,060 combinations .
The pair factors of 48 are (1, 48), (2, 24), (3, 16), (4, 12), (6, 8).
The number of combinations that are possible with 30 numbers, where numbers can’t be repeated, is 1,073,741,823 .
Answer and Explanation: The number of 7 number combinations between 1 and 49 is 85,900,584 .
Upto 100 there are 101 whole numbers . As whole numbers are all counting numbers including zero.
The sum of the first 40 positive integers divisible by 6 is 4920 .
The sum of each of the pairs of 1 and 100, 2 and 99, 3 and 98, . . ., and 50 and 51 is 101 . That is, each of these pairs of numbers adds to 101....
40 has 8 factors: 1, 2, 4, 5, 8, 10, 20, 40. Adding the factors up, the total is 90 .
Hint: there are three pairs of prime numbers whose sum is 40.
Since we are looking for two number that work with BOTH parts of the question, the correct answer is 25 and 15 . Why are these the two correct numbers? There you go! Best wishes!
Therefore, the first five multiples of 40 are 40, 80, 120, 160 and 200 .
∴ 40 has 8 positive factors .
Yes, since 40 has more than two factors i.e. 1, 2, 4, 5, 8, 10, 20, 40. In other words, 40 is a composite number because 40 has more than 2 factors.
