Answer
120
Work Step by Step
6,8,5,15
Use prime factorization to find the least common multiple of 6,8,5 and 15
Find the prime factorization for each number
6 = 2*3
8 = 2*2*2
5 = 5 *1
15 = 3*5
2 occur most often in the factorization of 6
2 * 2 occur most often in the factorization of 8
5 occur most often in the factorization of 5
3 occur most often in the factorization of 15
L.C.M. = 2*2*2*5 *3 = 120
