To determine the greatest common divisor between two numbers we must know the divisors of these two numbers
In this case, 13 and 44
The divisors of 13 are 1 and 13
The divisors of 44 are 1, 2, 4, 11, 22 and 44
We already know the divisors of each number
Since 13 is a prime number, it can only be divided by 1, and the same number
The number 44 does not have 13 as divisor but it does have 1 as the divisor
In conclusion, the greatest common factor between 13 and 44 is the 1 number
The answer is 1 number
