What is the greatest common factor of 8 and 12 and 30?

Answer 1

To find the greatest common factor (GCF) of 8, 12, and 30, we need to determine the largest number that divides evenly into all three numbers. The prime factors of 8 are 2 x 2 x 2, 12 is 2 x 2 x 3, and 30 is 2 x 3 x 5. To find the GCF, we identify the common prime factors among the three numbers, which are 2 and 2. Therefore, the GCF of 8, 12, and 30 is 2 x 2, which equals 4.

Answer 2

The greatest common factor of 8, 12, and 30 is 2

Answer 3

Factors of 8: 1, 2, 4, 8

Factors of 12: 1, 2, 3, 4, 6, 12

Factors of 30: 1, 2, 3, 5, 6, 10, 15, 30

GCF (8, 12, 30) = 2

Answer 4

2 is.
