Therefore, GCD of numbers 427, 364, 79, 520 is 1

Given Input Data is 427, 364, 79, 520

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

Prime Factorization of 427 is 7 x 61

Prime Factorization of 364 is 2 x 2 x 7 x 13

Prime Factorization of 79 is 79

Prime Factorization of 520 is 2 x 2 x 2 x 5 x 13

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(427, 364) = 22204

GCD(427, 364) = ( 427 x 364 ) / 22204

GCD(427, 364) = 155428 / 22204

GCD(427, 364) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 79

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

LCM(7, 79) = 553

GCD(7, 79) = ( 7 x 79 ) / 553

GCD(7, 79) = 553 / 553

GCD(7, 79) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 520

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

LCM(1, 520) = 520

GCD(1, 520) = ( 1 x 520 ) / 520

GCD(1, 520) = 520 / 520

GCD(1, 520) = 1

GCD of 427, 364, 79, 520 is 1
