Greatest Common Divisor (GCD) of 4 and 31

The Greatest Common Divisor (GCD) of 4 and 31 is the largest positive integer that divides both 4 and 31. Mathematically, the problem we are solving is:

GCD(4,31)

To solve the problem, we will list all the positive integers (divisors) that can be divided into 4 and 31. We will then compare the lists of divisors to find the greatest divisor they have in common.

Divisors of 4:
1, 2, and 4.

Divisors of 31:
1 and 31.

When we compare the lists of divisors above, we see that the largest number they have in common is 1. Thus, the Greatest Common Divisor (GCD) of 4 and 31 is:

GCD(4,31) = 1
