The Greatest Common Divisor of 16 and 28 is as follows:
4
To find the Greatest Common Divisor of 16 and 28, we first list all the divisors of 16
and all the divisors of 28. Then, we compare the two lists of divisors and pick the largest (greatest)
number that is on both lists, which will be the Greatest Common Divisor of 16 and 28.
Here is the list of 16 divisors: 1, 2, 4, 8, 16
And here is the list of 28 divisors: 1, 2, 4, 7, 14, 28
When we compare the two lists, we see that the greatest number they have in common is 4.
Therefore, once again, the answer to the question "What is the Greatest Common Divisor of 16 and 28?" is:
4
Note, the divisors of 16 are all the numbers you can divide into 16 with no remainder, and the divisors of 28 are
all the numbers you can divide into 28 with no remainder.
