Answer:
List the first five multiples of 30
The first 5 multiples of 30 are: 0, 30, 60, 90, 120.
What is the lowest common multiple of 12 and 30
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
