What is the greatest common factor of 30 and 50?

Answer 1

The GCF of 30 and 50 is 10.

One way to determine the greatest common factor is to find all the factors of the numbers and compare them.

The factors of 30 are 1, 2, 3, 5, 6, 10, 15, and 30.

The factors of 50 are 1, 2, 5, 10, 25, and 50.

The common factors are 1, 2, 5, and 10. Therefore, 10 is the greatest common factor.

The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together.

The prime factors of 30 are 2, 3, and 5.

The prime factors of 50 are 2, 5, and 5.

The prime factors they have in common are 2 and 5, so the greatest common factor is 2 x 5 = 10.
