Question

How do you find GCF of 12 and 30?

Answer 1

6

Explanation:

Divide each number into different multiples.
12:
- `1xx12`
- `2xx6`
- `3xx4`

30:
- `1xx30`
- `2xx15`
- `3xx10`
- `5xx6`

The greatest common factor (the largest number that both numbers divide into evenly), is 6.
No other numbers higher than 6 in these sets can be divided from both 12 and 30 evenly.
