1
00:00:00.000 --> 00:00:04.981
Here is the problem: Find the least common multiple of 6, 7, 8.

2
00:00:05.431 --> 00:00:07.869
Find the least common multiple of the numbers.

3
00:00:08.669 --> 00:00:10.678
Prime factorization of each number.

4
00:00:11.128 --> 00:00:14.007
Use the GCF to combine 6 and 7.

5
00:00:14.457 --> 00:00:18.033
Use the GCF to combine 42 and 8.

6
00:00:18.483 --> 00:00:24.381
Confirm with prime factors. Take every prime that appears, each with its largest exponent.

7
00:00:25.181 --> 00:00:27.863
So the answer is 168.

8
00:00:28.313 --> 00:00:33.735
168 is the smallest positive number that every input divides exactly.

9
00:00:34.535 --> 00:00:38.935
168 divided by 6 equals 28.

10
00:00:39.385 --> 00:00:43.309
168 divided by 7 equals 24.

11
00:00:43.759 --> 00:00:47.718
168 divided by 8 equals 21.
