The common factors of 70 and 50 are 1, 2, 5, and 10, since these are the numbers that divide both 70 and 50 without leaving a remainder.
What are the common factors of 50?
The common factors of 50 are 1, 2, 5, 10, 25, and 50, assuming you meant “common factors of 50 and 100,” as no other number was specified.
If you're looking for common factors with another number, list both numbers' factors and compare. For example, the common factors of 50 and 75 are 1, 5, and 25.
What are the factors of 70?
The positive factors of 70 are 1, 2, 5, 7, 10, 14, 35, and 70, and the negative factors are −1, −2, −5, −7, −10, −14, −35, and −70.
To find them, divide 70 by each integer starting from 1. If the result is a whole number, it's a factor. You can also use prime factorization: 70 = 2 × 5 × 7, which helps verify all possible combinations.
What are the factors of 72 and 50?
The factors of 50 are 1, 2, 5, 10, 25, and 50, and the factors of 72 are 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, and 72.
When comparing both lists, the common factors are 1 and 2, which means the greatest common factor (GCF) of 50 and 72 is 2.
What are the factors of 50 and 75?
The factors of 50 are 1, 2, 5, 10, 25, and 50, and the factors of 75 are 1, 3, 5, 15, 25, and 75.
To find common factors, compare both lists—here, 1, 5, and 25 appear in both. The greatest common factor (GCF) of 50 and 75 is therefore 25.
What are two factors of 70?
Any two numbers from the set {1, 2, 5, 7, 10, 14, 35, 70} are factors of 70, such as 2 and 35.
Factors come in pairs that multiply to 70. For instance, 2 × 35 = 70, so both are valid factors. You can pick any two from the full list depending on what you need them for.
What is the factor of 71?
Since 71 is a prime number, its only factors are 1 and 71.
Prime numbers are numbers greater than 1 that have no positive divisors other than 1 and themselves. This makes 71 a classic example of a prime number.
What are 5 factors of 50?
Five factors of 50 are 1, 2, 5, 10, and 25—the others are 50 itself.
You can use these for simplifying fractions, finding divisors, or solving math problems. If you need more, the full list includes 1, 2, 5, 10, 25, and 50.
What is the HCF of 50 and 70?
The highest common factor (HCF) of 50 and 70 is 10.
You can find the HCF using the Euclidean algorithm: divide 70 by 50 to get a remainder of 20, then divide 50 by 20 to get a remainder of 10, and finally divide 20 by 10 to get zero. The last non-zero remainder is the HCF, which is 10.
What is the multiple of 50?
The first few multiples of 50 are 50, 100, 150, 200, 250, and 300.
Multiples are numbers you get by multiplying 50 by an integer (e.g., 50×1=50, 50×2=100). These are useful in problems involving scheduling, currency, or measurements.
What is the HCF of 50 and 72?
The highest common factor (HCF) of 50 and 72 is 2.
To find this, list the factors of both numbers and identify the largest one in both lists. Alternatively, use prime factorization: 50 = 2 × 5², 72 = 2³ × 3²—only the single 2 appears in both, so the HCF is 2.
What is the HCF of 10?
The HCF of 10 and 15 is 5.
Prime factorization helps here: 10 = 2 × 5, 15 = 3 × 5. The only common prime factor is 5, so the HCF is 5. If you meant a different pair, replace 15 with your second number.
What is the LCM of 50 and 72?
The least common multiple (LCM) of 50 and 72 is 1800.
Use the formula LCM(a,b) = |a × b| / GCF(a,b). Here, GCF(50,72)=2, so LCM = (50×72)/2 = 1800. The LCM is the smallest number both 50 and 72 divide into without a remainder.
What is the common multiple of 50 and 75?
The least common multiple (LCM) of 50 and 75 is 150.
To calculate, list multiples of each number until you find a match: 50 (50, 100, 150, …) and 75 (75, 150, …). The first overlap is 150, which is the smallest number both divide evenly into.
What is the GCF of 30 and 75?
The greatest common factor (GCF) of 30 and 75 is 15.
Prime factorization helps: 30 = 2 × 3 × 5, 75 = 3 × 5². The common primes are 3 and 5, so multiply them: 3 × 5 = 15. This is the largest number that divides both 30 and 75 evenly.
What is the GCF of 7 and 50?
The greatest common factor (GCF) of 7 and 50 is 1.
Since 7 is a prime number and doesn't divide 50 evenly (50 ÷ 7 ≈ 7.14), the only common factor is 1. Honestly, this is the best example of numbers being "coprime."
