1

Answer 2

The GCF of 36, 45, and 56 is 1.

The prime factorization of 36 is 2*2*3*3

Answer 3

1. The factors of 45 are: 1 3 5 9 15 45
2. The factors of 56 are: 1 2 4 7 8 14 28 56

Answer 4

2 x 2 x 2 x 3 = 24

2 x 2 x 2 x 7 = 56

2 x 2 x 2 = 8, the GCF

Answer 5

3 x 3 x 5 = 45

2 x 2 x 3 x 5 = 60

3 x 5 = 15, the GCF

Answer 6

3 x 3 x 5 = 45

2 x 2 x 2 x 7 = 56
