We found the divisors of 84, 88, 31, 89 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 84, 88, 31, 89 is 1.

Therefore, GCD of numbers 84, 88, 31, 89 is 1

Given Input Data is 84, 88, 31, 89

Make a list of Prime Factors of all the given numbers initially

Prime Factorization of 84 is 2 x 2 x 3 x 7

Prime Factorization of 88 is 2 x 2 x 2 x 11

Prime Factorization of 31 is 31

Prime Factorization of 89 is 89

The above numbers do not have any common prime factor. So GCD is 1

Step1:

Let's calculate the GCD of first two numbers

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(84, 88) = 1848

GCD(84, 88) = ( 84 x 88 ) / 1848

GCD(84, 88) = 7392 / 1848

GCD(84, 88) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 31

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(4, 31) = 124

GCD(4, 31) = ( 4 x 31 ) / 124

GCD(4, 31) = 124 / 124

GCD(4, 31) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 89

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(1, 89) = 89

GCD(1, 89) = ( 1 x 89 ) / 89

GCD(1, 89) = 89 / 89

GCD(1, 89) = 1

GCD of 84, 88, 31, 89 is 1
