What is the smallest number that has 2,3,4,5 and 6 as factors
Number Factorization How many 2's How many 3's How many 5's
2 2 1 0 0
3 = 3 0 1 0
4 = 2·2 2 0 0
5 = 5 0 0 1
6 = 2·3 1 1 0
So the most number of 2's any one of them has is 2.
the most number of 3's any one of them has is 1.
the most number of 5's any one of them has is 1.
So the least common multiple of 2,3,4,5,and 6, has 2 2's, 1 3, and 1 5
LCM = 2·2·3·5 = 60
