So the Greatest Common Divisior 86, 57, 31 is 1.

Therefore, GCD of numbers 86, 57, 31 is 1

Given Input Data is 86, 57, 31

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

Prime Factorization of 86 is 2 x 43

Prime Factorization of 57 is 3 x 19

Prime Factorization of 31 is 31

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(86, 57) = 4902

GCD(86, 57) = ( 86 x 57 ) / 4902

GCD(86, 57) = 4902 / 4902

GCD(86, 57) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 31

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

LCM(1, 31) = 31

GCD(1, 31) = ( 1 x 31 ) / 31

GCD(1, 31) = 31 / 31

GCD(1, 31) = 1

GCD of 86, 57, 31 is 1
