The Greatest Common Divisor of 38 and 15 is as follows:
1
To find the Greatest Common Divisor of 38 and 15, we first list all the divisors of 38
and all the divisors of 15. 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 38 and 15.
Here is the list of 38 divisors: 1, 2, 19, 38
And here is the list of 15 divisors: 1, 3, 5, 15
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 38 and 15?" is:
1
Note, the divisors of 38 are all the numbers you can divide into 38 with no remainder, and the divisors of 15 are
all the numbers you can divide into 15 with no remainder.
