We found the divisors of 56, 14, 83, 81 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 56, 14, 83, 81 is 1.

Therefore, GCD of numbers 56, 14, 83, 81 is 1

Given Input Data is 56, 14, 83, 81

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

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

Prime Factorization of 14 is 2 x 7

Prime Factorization of 83 is 83

Prime Factorization of 81 is 3 x 3 x 3 x 3

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(56, 14) = 56

GCD(56, 14) = ( 56 x 14 ) / 56

GCD(56, 14) = 784 / 56

GCD(56, 14) = 14

Step2:

Here we consider the GCD from the above i.e. 14 as first number and the next as 83

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

LCM(14, 83) = 1162

GCD(14, 83) = ( 14 x 83 ) / 1162

GCD(14, 83) = 1162 / 1162

GCD(14, 83) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 81

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

LCM(1, 81) = 81

GCD(1, 81) = ( 1 x 81 ) / 81

GCD(1, 81) = 81 / 81

GCD(1, 81) = 1

GCD of 56, 14, 83, 81 is 1
