Question

write the steps to find LCM of three number​

Answer 1

• Answer:
• One way to find the least common multiple of two numbers is to first list the prime factors of each number. Then multiply each factor the greatest number of times it occurs in either number. If the same factor occurs more than once in both numbers, you multiply the factor the greatest number of times it occurs.

Answer 2

Answer:

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.
