What is the gcf for 30 180 450?

Answer 1

The GCF of 30 180 and 450 is 30. You get 1, 6 and 15 left over, of which there are no further common factors aside from 1.

Answer 2

To find the greatest common factor (GCF) for 30, 180, and 450, we need to determine the largest number that divides evenly into all three numbers. First, we find the prime factors of each number: 30 = 2 x 3 x 5, 180 = 2 x 2 x 3 x 3 x 5, and 450 = 2 x 3 x 3 x 5 x 5. The GCF is the product of the common prime factors raised to the lowest power, which in this case is 2 x 3 x 5 = 30. Therefore, the GCF for 30, 180, and 450 is 30.
