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
