Chapter 4.2, Problem 3C

To determine

To find the greatest common factor

Answer to Problem 3C

8

Explanation of Solution

Given Information: 16, 32, 40

Formula used: Using Factorization

Calculation:

Here, break both the numbers into its factors respectively.

So, 16 may be written as $16=2\times 2\times 2\times 2$

And 32 may be written as $32=2\times 2\times 2\times 2\times 2$

And 40 may be written as $40=2\times 2\times 2\times 5$

Since $2\times 2\times 2$ is common in all the numbers. Hence , the greatest common factor is 8.
