We found the divisors of 31, 93, 86, 56 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 31, 93, 86, 56 is 1.

Therefore, GCD of numbers 31, 93, 86, 56 is 1

Given Input Data is 31, 93, 86, 56

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

Prime Factorization of 31 is 31

Prime Factorization of 93 is 3 x 31

Prime Factorization of 86 is 2 x 43

Prime Factorization of 56 is 2 x 2 x 2 x 7

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(31, 93) = 93

GCD(31, 93) = ( 31 x 93 ) / 93

GCD(31, 93) = 2883 / 93

GCD(31, 93) = 31

Step2:

Here we consider the GCD from the above i.e. 31 as first number and the next as 86

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

LCM(31, 86) = 2666

GCD(31, 86) = ( 31 x 86 ) / 2666

GCD(31, 86) = 2666 / 2666

GCD(31, 86) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 56

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

LCM(1, 56) = 56

GCD(1, 56) = ( 1 x 56 ) / 56

GCD(1, 56) = 56 / 56

GCD(1, 56) = 1

GCD of 31, 93, 86, 56 is 1
