Question

how can you use number patterns to find the least common multiple of 120 and 360

Answer 1

Given: 120 & 360

 

Find:

Least common multiple of 120 and 360   Solution:  

In order to use the number patterns to find the least common multiple of 120 and 360, we need to factor each value first and then, we choose all the factors that appear in any of the column and then we multiply them.

 

120:    2 2 2 3   5 360:    2 2 2 3 3 5 LCM:    2 2 2 3 3 5

Therefore, the Least Common Multiple (LCM) of 120 and 360 is:   2 x 2 x 2 x 3 x 3 x 5 = 360
