Therefore, GCD of numbers 476, 203, 172, 479 is 1

Given Input Data is 476, 203, 172, 479

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

Prime Factorization of 476 is 2 x 2 x 7 x 17

Prime Factorization of 203 is 7 x 29

Prime Factorization of 172 is 2 x 2 x 43

Prime Factorization of 479 is 479

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(476, 203) = 13804

GCD(476, 203) = ( 476 x 203 ) / 13804

GCD(476, 203) = 96628 / 13804

GCD(476, 203) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 172

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

LCM(7, 172) = 1204

GCD(7, 172) = ( 7 x 172 ) / 1204

GCD(7, 172) = 1204 / 1204

GCD(7, 172) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 479

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

LCM(1, 479) = 479

GCD(1, 479) = ( 1 x 479 ) / 479

GCD(1, 479) = 479 / 479

GCD(1, 479) = 1

GCD of 476, 203, 172, 479 is 1
