Question

find the lcm of 9,16,25​

Answer 1

List all prime factors for each number.

Prime Factorization of 9 is:

3 x 3 => 32

Prime Factorization of 16 is:

2 x 2 x 2 x 2 => 24

Prime Factorization of 25 is:

5 x 5 => 52

For each prime factor, find where it occurs most often as a factor and write it that many times in a new list.

The new superset list is

2, 2, 2, 2, 3, 3, 5, 5

Multiply these factors together to find the LCM.

LCM = 2 x 2 x 2 x 2 x 3 x 3 x 5 x 5 = 3600

In exponential form:

LCM = 24 x 32 x 52 = 3600

LCM = 3600

Therefore,

LCM(9, 16, 25) = 3600
