What is the first task in using the step approach to finding the greatest common divisor

Divide numerator into denominator

Step-by-step explanation:

We have to determine the first task in using the step approach to finding the greatest common divisor.

The answer will be - Divide numerator into denominator

GCD is largest number that divides the given numbers.

The first step is to find the divisors of given numbers.

For example- Lets say we want to know the gcd of (42,36)

First we will divide 42 by 36 to get a quotient of 1 and a remainder of 6.

Then we will divide 36 by 6 to get a quotient of 6 and a remainder of 0.

So, 6 is the gcd.
