1
00:00:00.000 --> 00:00:05.178
Here is the problem: Find the least common multiple of 8, 12, 18.

2
00:00:05.628 --> 00:00:08.008
Find the least common multiple of the numbers.

3
00:00:08.808 --> 00:00:10.863
Prime factorization of each number.

4
00:00:11.313 --> 00:00:14.401
Use the GCF to combine 8 and 12.

5
00:00:14.851 --> 00:00:18.915
Use the GCF to combine 24 and 18.

6
00:00:19.365 --> 00:00:25.158
Confirm with prime factors. Take every prime that appears, each with its largest exponent.

7
00:00:25.958 --> 00:00:27.885
So the answer is 72.

8
00:00:28.335 --> 00:00:33.362
72 is the smallest positive number that every input divides exactly.

9
00:00:34.162 --> 00:00:37.064
72 divided by 8 equals 9.

10
00:00:37.515 --> 00:00:40.731
72 divided by 12 equals 6.

11
00:00:41.181 --> 00:00:44.316
72 divided by 18 equals 4.
