Greatest Common Divisior

We found the divisors of 56, 51, 38 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 56, 51, 38 is 1.

Therefore, GCD of numbers 56, 51, 38 is 1

Given Input Data is 56, 51, 38

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 51 is 3 x 17

Prime Factorization of 38 is 2 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(56, 51) = 2856

GCD(56, 51) = ( 56 x 51 ) / 2856

GCD(56, 51) = 2856 / 2856

GCD(56, 51) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 38

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

LCM(1, 38) = 38

GCD(1, 38) = ( 1 x 38 ) / 38

GCD(1, 38) = 38 / 38

GCD(1, 38) = 1

GCD of 56, 51, 38 is 1
