The LCM of 12 and 18 is 36.

The prime factors of 12 are 2, 2 and 3

The prime factors of 18 are 2, 3 and 3.

So, to calculate the lowest common multiple of the two numbers we need to include all the factors of each number

As there is one 2 in 18 but two in 12, we need to have two 2s in the procedure.

As there is one 3 in 12 but two in 18, we need to have two 3s in the procedure.

This means that 2, 2, 3 and 3 need to be multiplied together to produce the LCM.

2 x 2 x 3 x 3 = 36.
The LCM is: 36
