Given Input Data is 172, 868, 647, 463

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

Prime Factorization of 172 is 2 x 2 x 43

Prime Factorization of 868 is 2 x 2 x 7 x 31

Prime Factorization of 647 is 647

Prime Factorization of 463 is 463

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(172, 868) = 37324

GCD(172, 868) = ( 172 x 868 ) / 37324

GCD(172, 868) = 149296 / 37324

GCD(172, 868) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 647

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

LCM(4, 647) = 2588

GCD(4, 647) = ( 4 x 647 ) / 2588

GCD(4, 647) = 2588 / 2588

GCD(4, 647) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 463

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

LCM(1, 463) = 463

GCD(1, 463) = ( 1 x 463 ) / 463

GCD(1, 463) = 463 / 463

GCD(1, 463) = 1

GCD of 172, 868, 647, 463 is 1
