| 00:19 | mono meals that are just numbers like 30 and 42 | |
| 00:24 | . We start by setting up a factor tree for | |
| 00:27 | each of those numbers , 30 is just three times | |
| 00:32 | 10 And 10 is two times 5 . 42 is | |
| 00:39 | seven times 6 and six is 2 times three . | |
| 00:45 | Our next step is to take a look at those | |
| 00:47 | factor trees and find the factors that are in common | |
| 00:51 | to both numbers notice That both numbers have a factor | |
| 00:57 | of three and both numbers Have a factor of two | |
| 01:03 | . Once you've found the factors that match up simply | |
| 01:07 | multiply those factors together To get the greatest common factor | |
| 01:11 | of the two numbers . So since the threes match | |
| 01:14 | up and the twos match up , The greatest common | |
| 01:17 | factor is three times 2 or six and that's the | |
| 01:26 | answer . |
