Divide it by 9
They are: 3*3*5 = 45
use 45 cents and 1 5 cent coin.
Use a factor tree. 45 15,3 5,3,3
3 x 3 x 5 = 45
Make the lower numbers the same firstly 3/5 x 9/9 = 27/45 2/9 x 5/5 = 10/45 27/45 - 10/45 = 17/45
5 and 9 are factors of 45. The GCF of 5 and 45 is 5. The LCM of 5 and 45 is 45.
lcm(5, 3) = 15 lcm(5, 45) = 45 lcm(3, 45) = 45 lcm(5, 3, 45) = 45
As a product of its prime factors: 3*3*5 = 45 Or as: 23+19+3 = 45
45 15,3 5,3,3 3 x 3 x 5 = 45

1 x 45, 3 x 15, 5 x 9, 9 x 5, 15 x 3, 45 x 1.
3 x 3 x 5 = 45
