Question

Explain how to find the least common multiple of two numbers.

Answer 1

First convert numbers into prime numbers. find which number(s) is/are repeating. Multiply all numbers execpt for the number that repeat. Multiply those once.

Explanation:

12 = 3*2*2

14 = 2*7

One 2 repeats

3*2*2*7 = 21*4 = 84

Lcm(12, 14) = 84

Answer 2

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.
