We found the divisors of 56, 7, 53, 86 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 56, 7, 53, 86 is 1.

Therefore, GCD of numbers 56, 7, 53, 86 is 1

Given Input Data is 56, 7, 53, 86

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 7 is 7

Prime Factorization of 53 is 53

Prime Factorization of 86 is 2 x 43

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, 7) = 56

GCD(56, 7) = ( 56 x 7 ) / 56

GCD(56, 7) = 392 / 56

GCD(56, 7) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 53

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

LCM(7, 53) = 371

GCD(7, 53) = ( 7 x 53 ) / 371

GCD(7, 53) = 371 / 371

GCD(7, 53) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 86

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

LCM(1, 86) = 86

GCD(1, 86) = ( 1 x 86 ) / 86

GCD(1, 86) = 86 / 86

GCD(1, 86) = 1

GCD of 56, 7, 53, 86 is 1
