Therefore, GCD of numbers 83, 664, 647, 244 is 1

Given Input Data is 83, 664, 647, 244

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

Prime Factorization of 83 is 83

Prime Factorization of 664 is 2 x 2 x 2 x 83

Prime Factorization of 647 is 647

Prime Factorization of 244 is 2 x 2 x 61

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(83, 664) = 664

GCD(83, 664) = ( 83 x 664 ) / 664

GCD(83, 664) = 55112 / 664

GCD(83, 664) = 83

Step2:

Here we consider the GCD from the above i.e. 83 as first number and the next as 647

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

LCM(83, 647) = 53701

GCD(83, 647) = ( 83 x 647 ) / 53701

GCD(83, 647) = 53701 / 53701

GCD(83, 647) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 244

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

LCM(1, 244) = 244

GCD(1, 244) = ( 1 x 244 ) / 244

GCD(1, 244) = 244 / 244

GCD(1, 244) = 1

GCD of 83, 664, 647, 244 is 1
