The Greatest Common Divisor of 34 and 21 is as follows:
1
To find the Greatest Common Divisor of 34 and 21, we first list all the divisors of 34
and all the divisors of 21. 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 34 and 21.
Here is the list of 34 divisors: 1, 2, 17, 34
And here is the list of 21 divisors: 1, 3, 7, 21
When we compare the two lists, we see that the greatest number they have in common is 1.
Therefore, once again, the answer to the question "What is the Greatest Common Divisor of 34 and 21?" is:
1
Note, the divisors of 34 are all the numbers you can divide into 34 with no remainder, and the divisors of 21 are
all the numbers you can divide into 21 with no remainder.
