The Greatest Common Divisor of 91 and 78 is as follows:
13
To find the Greatest Common Divisor of 91 and 78, we first list all the divisors of 91
and all the divisors of 78. 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 91 and 78.
Here is the list of 91 divisors: 1, 7, 13, 91
And here is the list of 78 divisors: 1, 2, 3, 6, 13, 26, 39, 78
When we compare the two lists, we see that the greatest number they have in common is 13.
Therefore, once again, the answer to the question "What is the Greatest Common Divisor of 91 and 78?" is:
13
Note, the divisors of 91 are all the numbers you can divide into 91 with no remainder, and the divisors of 78 are
all the numbers you can divide into 78 with no remainder.
