Least Common Multiple (LCM) of 9 and 15

Least Common Multiple Can we calculated in different ways. You can calculate LCM through Prime Factors and the second is simple. I will describe all the methods possible to calculate the LCM of 9 and 15.

Method 1:  LCM of 9 and 15

Multiples of 15 = 15, 30, 45, 60, 75, 90, ………

Multiples of 9 = 9, 18, 36, 45, 54, 63, 72, 81, 90,…….

Common Multiples of 9 and 15 = 45, 90

Lowest Common Multiples of 9 and 15 = 45

The LCM of 9 and 15 is 45.

Method 2:  LCM of 9 and 15

Find the Prime factors of 9 = 3 X 3

Find the Prime Factor of 15 = 5 X 3

Least Common Multiples of 9 and 15 = 3 X 3 X 5 = 45

Method 3:  LCM of 9 and 15

Find the Least Common Multiples of 9 and 15.

3 9, 15
3 3, 5
5 1, 5
  1, 1

Least Common Multiples of 9 and 15 = 3 X 3 X 5 = 45
