00:00:00.000 --> 00:00:04.400
Here is the problem: Find the least common multiple of 25, 40.

2
00:00:04.850 --> 00:00:07.335
Find the least common multiple of the numbers.

3
00:00:08.135 --> 00:00:10.155
Prime factorization of each number.

4
00:00:10.605 --> 00:00:13.960
Use the GCF to combine 25 and 40.

5
00:00:14.410 --> 00:00:20.145
Confirm with prime factors. Take every prime that appears, each with its largest exponent.

6
00:00:20.945 --> 00:00:22.733
So the answer is 200.

7
00:00:23.183 --> 00:00:27.665
200 is the smallest positive number that every input divides exactly.

8
00:00:28.464 --> 00:00:31.448
200 divided by 25 equals 8.

9
00:00:31.898 --> 00:00:34.638
200 divided by 40 equals 5.
