1, 3, 5, 9, 15, 45
The common factors of 20 and 45 are 1 and 5 Factors of 45: 1 and 45, 3 and 15, and 5 and 9 Factors of 20: 1 and 20, 2 and 10, and 4 and 5 So the common factors are 1 and 5.
1, 3, 5, 9, 15, 45.
The factors of 15 are: 1, 3, 5, 15The factors of 45 are: 1, 3, 5, 9, 15, 45
1, 3, 5, 9, 15, 45
1/5 of 45 = 1/5 x 45 = 45 ÷ 5 = 9
one fifth of 45 is:1/5 x 45 = 45/5= 45 ÷ 5= 9

The common factors of 20 and 45 are 1 and 5 Factors of 45: 1 and 45, 3 and 15, and 5 and 9 Factors of 20: 1 and 20, 2 and 10, and 4 and 5 So the common factors are 1 and 5.
1, 3, 5, 9, 15, 45
The factors of 5 are 1 and 5. The factors of 45 are 1, 3, 5, 9, 15, and 45.
The factors of 45 are 1, 45, 9 and 5.and 15 and 3
45/9 = 5/1 or 5
5 / 1/9 = 45
Factors of 45: 1, 3, 5, 9, 15, 45 Factors of 15: 1, 3, 5, 15 Factors of 5: 1, 5 GCF (45, 15, 5) = 5
1 ninth of 45 is 5
45.(45 * 1)(5 * 9)
