Find the gcf of 24 and 80 and find the lcm of 24 and 40

LCM is 120. GCF is 8.

Step-by-step explanation:

LCM of 24: 3 and 8,

                            2, 4

                                2, 2

You need to prime factorize first so 24: 2 x 2 x 2 x 3

LCM of 40: 4 and 10

                  2, 2      2, 5

So 2 x 2 x 2 x 5

Greater number of each of them: 2 x 2 x 2 x 3 x 5= 120

GCF of 24:

Factors of 24: 1, 2, 3, 4, 6, 8, 12

Factors of 80: 1, 2, 4, 5, 8, 10, 20

So the GCF is 8

Hope my answer has helped you!
