Exercise 11 Page 168

The least common multiple (LCM) is the least multiple shared by two or more numbers, not including zero.

60

Practice makes perfect

The least common multiple (LCM) is the least multiple shared by two or more numbers, not including zero. The first step to find the LCM of two or more numbers is to write the prime factorization of each number.

Given Number	Prime Factorization
12	2* 2* 3
5	5

Then, we list the greatest number of times each factor appears in either prime factorization and multiply these factors. 2* 2* 3* 5=60
