## What’s the GCF for 75 and 30?

The prime numbers 5 and 3 are both factors that are common to 30 and 75.

The product of these factors is 3×5 = 15.

Thus, the “Greatest Common Factor” of 30 and 75 is 15.

To check this result, divide 15 into 30 and then into 75, and verify that in each case the result is a whole number..

## What is the GCF of 12 and 30?

Earlier we found that the Common Factors of 12 and 30 are 1, 2, 3 and 6, and so the Greatest Common Factor is 6. The Greatest Common Factor of 12 and 30 is 6.

## What is the GCF of 15 and 20?

We found the factors and prime factorization of 15 and 20. The biggest common factor number is the GCF number. So the greatest common factor 15 and 20 is 5.

## What is the GCF of 8 and 24?

Findthe greatest common factor (GCF) of 8 and 24. The factors of 8 are 1, 2, 4, and 8. The factors of 24 are 1, 2, 3, 4, 6, 8, 12, and 24. The largest factor that is in both these lists is 8.

## What is the GCF of 12 and 18?

In terms of numbers, the greatest common factor (gcf) is the largest natural number that exactly divides two or more given natural numbers. Example 1: 6 is the greatest common factor of 12 and 18.

## What is the greatest common factor of 84?

Greatest common factor (GCF) of 84 and 92 is 4. We will now calculate the prime factors of 84 and 92, than find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 84 and 92.

## What are the factors of 84?

Factors of 84: 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 84. Prime factorization: 84 = 2 x 2 x 3 x 7 which can also be written 2² x 3 x 7.

## How do you find the greatest factor?

The greatest common factor, or GCF, is the greatest factor that divides two numbers. To find the GCF of two numbers: List the prime factors of each number. Multiply those factors both numbers have in common.

## What is the GCF of 21 42 and 84?

The common factors of 42 and 84 are 42, 21, 14, 7, 6, 3, 2, 1, intersecting the two sets above. In the intersection factors of 42 ∩ factors of 84 the greatest element is 42. Therefore, the greatest common factor of 42 and 84 is 42.

## What is the greatest factor of 42 and 84?

We found the factors and prime factorization of 42 and 84. The biggest common factor number is the GCF number. So the greatest common factor 42 and 84 is 42.

## What is the GCF of 70 and 30?

The common factors of 30 and 70 are 10, 5, 2, 1, intersecting the two sets above. In the intersection factors of 30 ∩ factors of 70 the greatest element is 10. Therefore, the greatest common factor of 30 and 70 is 10.

## What is the GCF of 15 and 35?
