To find the Least Common Multiple, you factor both values, then multiply the highest exponent of each factor. (You are removing common factors to find a multiple that is smaller than just multiplying the two numbers together.)
Example: for 72 and 108, the obvious multiple is 72 x 108 = 7776, but we can find a smaller one.
72 = 2 x 2 x 2 x 3 x 3 --- (23 x 32)
108 = 2 x 2 x 3 x 3 x 3 --- (22 x 33)
The highest exponent of each factor is 23 and 33, and 8 x 27 = 216
You can see that 216 is (72 x 3) or (108 x 2). There is no smaller even multiple.

Rather than using the exponential formula, you can also multiply the common factors by the uncommon factors.
Common factors = 2 x 2 x 3 x 3 (36)
Uncommon factors = 2 and 3 (6) and 36 x 6 = 216

How we can find the LCM OF 36 , 72 & 108?
Step 1 Find the prime factors of each number 36 = 2×2×3×3 = 2²×3² 72 = 2³×3² 108 = 2²×3³ Step 2 Find LCM L - Highest (Find the number with the highest exponent) C - Common (Find the common number EG. 2 and 3) M - Missing ( Take what ever is missing that is not common) LCM : 2³×3³ = 216 Your LCM is 216
