Apply the distributive property to factor out the greatest common factor.

16+36

well, you have

4*4 + 4*9
so, what's next?

To apply the distributive property and factor out the greatest common factor of 16 and 36, we first need to find the greatest common factor (GCF) of the two numbers.

The factors of 16 are: 1, 2, 4, 8, 16.
The factors of 36 are: 1, 2, 3, 4, 6, 9, 12, 18, 36.

The common factors of 16 and 36 are: 1, 2, 4.

The greatest common factor (GCF) is 4.

Now, we can rewrite the expression 16 + 36 as:
4 * 4 + 4 * 9

Using the distributive property, we can factor out the GCF of 4:
4 * (4 + 9)

Therefore, the expression 16 + 36, when factored out by the greatest common factor, becomes 4 * (4 + 9).
