Greatest Common Divisior

We found the divisors of 123, 422, 777, 724 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 123, 422, 777, 724 is 1.

Therefore, GCD of numbers 123, 422, 777, 724 is 1

Given Input Data is 123, 422, 777, 724

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

Prime Factorization of 123 is 3 x 41

Prime Factorization of 422 is 2 x 211

Prime Factorization of 777 is 3 x 7 x 37

Prime Factorization of 724 is 2 x 2 x 181

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(123, 422) = 51906

GCD(123, 422) = ( 123 x 422 ) / 51906

GCD(123, 422) = 51906 / 51906

GCD(123, 422) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 777

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

LCM(1, 777) = 777

GCD(1, 777) = ( 1 x 777 ) / 777

GCD(1, 777) = 777 / 777

GCD(1, 777) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 724

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

LCM(1, 724) = 724

GCD(1, 724) = ( 1 x 724 ) / 724

GCD(1, 724) = 724 / 724

GCD(1, 724) = 1

GCD of 123, 422, 777, 724 is 1
