Given Input Data is 642, 258, 331, 541

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

Prime Factorization of 642 is 2 x 3 x 107

Prime Factorization of 258 is 2 x 3 x 43

Prime Factorization of 331 is 331

Prime Factorization of 541 is 541

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(642, 258) = 27606

GCD(642, 258) = ( 642 x 258 ) / 27606

GCD(642, 258) = 165636 / 27606

GCD(642, 258) = 6

Step2:

Here we consider the GCD from the above i.e. 6 as first number and the next as 331

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

LCM(6, 331) = 1986

GCD(6, 331) = ( 6 x 331 ) / 1986

GCD(6, 331) = 1986 / 1986

GCD(6, 331) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 541

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

LCM(1, 541) = 541

GCD(1, 541) = ( 1 x 541 ) / 541

GCD(1, 541) = 541 / 541

GCD(1, 541) = 1

GCD of 642, 258, 331, 541 is 1
