Gcf problem set a
gcf (16,24)
gcf (15, 45, 60)

8

15

Step-by-step explanation:

To find the GCF of numbers, first find the prime factorizations of the numbers. The GCF is the product of common factors with lowest exponent.

GCF (16, 24)

16 = 2^4

24 = 2^3 * 3

GCF = 2^3 = 8

GCF (15, 45, 60)

15 = 3 * 5

45 = 3^3 * 5

60 = 2^2 * 3 * 5

GCF = 3 * 5 = 15
