# How do you find GCF of 12 and 30?

Mar 3, 2018

6

#### Explanation:

Divide each number into different multiples.
12:
- $1 \times 12$
- $2 \times 6$
- $3 \times 4$

30:
- $1 \times 30$
- $2 \times 15$
- $3 \times 10$
- $5 \times 6$

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.
