...
For example, for LCM (12,30) we find:
- Prime factorization of 12 = 2 × 2 × 3.
- Prime factorization of 30 = 2 × 3 × 5.
- Using all prime numbers found as often as each occurs most often we take 2 × 2 × 3 × 5 = 60.
- Therefore LCM (12,30) = 60.
How do you find the LCM step by step?
LCM by Listing Method
- Step 1: List the first few multiples of A and B.
