We found the divisors of 13, 51, 57 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 13, 51, 57 is 1.

Therefore, GCD of numbers 13, 51, 57 is 1

Given Input Data is 13, 51, 57

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

Prime Factorization of 13 is 13

Prime Factorization of 51 is 3 x 17

Prime Factorization of 57 is 3 x 19

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(13, 51) = 663

GCD(13, 51) = ( 13 x 51 ) / 663

GCD(13, 51) = 663 / 663

GCD(13, 51) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 57

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

LCM(1, 57) = 57

GCD(1, 57) = ( 1 x 57 ) / 57

GCD(1, 57) = 57 / 57

GCD(1, 57) = 1

GCD of 13, 51, 57 is 1
