1
00:00:00.000 --> 00:00:04.400
Here is the problem: Find the least common multiple of 12, 18.

2
00:00:04.850 --> 00:00:07.404
Find the least common multiple of the numbers.

3
00:00:08.204 --> 00:00:10.143
Prime factorization of each number.

4
00:00:10.593 --> 00:00:14.146
Use the GCF to combine 12 and 18.

5
00:00:14.596 --> 00:00:20.413
Confirm with prime factors. Take every prime that appears, each with its largest exponent.

6
00:00:21.213 --> 00:00:23.187
So the answer is 36.

7
00:00:23.637 --> 00:00:28.293
36 is the smallest positive number that every input divides exactly.

8
00:00:29.093 --> 00:00:32.019
36 divided by 12 equals 3.

9
00:00:32.469 --> 00:00:35.708
36 divided by 18 equals 2.
