Answer:
1
Step-by-step explanation:
factors of 32 = 1, 2, 4, 8, 16, 32; factors of 45 = 1, 3, 5, 9, 15, 45) and choose the greatest factor that exactly divides both 32 and 45 is 1
GCF = 1
factors of 32: 1,2,4,8,16,32
1 x 32
2 x 16
4 x 8
factors of 45: 1,3,5,9,15,45
1 x 45
3 x 15
5 x 9
only value in common is 1
