6

Explanation of Solution

Given Information: 12,30

Formula used: Using Factorization

Calculation:

Here, break both the numbers into its factors respectively.

So, 12 may be written as $12=2\times 3\times 2$

And 30 may be written as $30=2\times 3\times 5$

Since $2\times 3$ is common in all the numbers. Hence , the greatest common factor is 6.
