Question

What is the lowest common multiple of 6, 12 and 30?

Answer 1

LCM(6, 12, 30) = 60

Explanation:

Find the prime factorization of each number.

6 = 2 * 3

12 = 2 * 2 * 3

30 = 2 * 3 * 5

Multiply all factors, though only once for each factor that repeats in all three numbers.

2 * 2 * 3 * 5 = 60

Answer 2

Answer: 60

60/6=10
60/12=5
60/30=2
