Given Input Data is 171, 366, 558, 653

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

Prime Factorization of 171 is 3 x 3 x 19

Prime Factorization of 366 is 2 x 3 x 61

Prime Factorization of 558 is 2 x 3 x 3 x 31

Prime Factorization of 653 is 653

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(171, 366) = 20862

GCD(171, 366) = ( 171 x 366 ) / 20862

GCD(171, 366) = 62586 / 20862

GCD(171, 366) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 558

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

LCM(3, 558) = 558

GCD(3, 558) = ( 3 x 558 ) / 558

GCD(3, 558) = 1674 / 558

GCD(3, 558) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 653

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

LCM(3, 653) = 1959

GCD(3, 653) = ( 3 x 653 ) / 1959

GCD(3, 653) = 1959 / 1959

GCD(3, 653) = 1

GCD of 171, 366, 558, 653 is 1
