Given Input Data is 438, 652, 555, 602

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

Prime Factorization of 438 is 2 x 3 x 73

Prime Factorization of 652 is 2 x 2 x 163

Prime Factorization of 555 is 3 x 5 x 37

Prime Factorization of 602 is 2 x 7 x 43

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(438, 652) = 142788

GCD(438, 652) = ( 438 x 652 ) / 142788

GCD(438, 652) = 285576 / 142788

GCD(438, 652) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 555

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

LCM(2, 555) = 1110

GCD(2, 555) = ( 2 x 555 ) / 1110

GCD(2, 555) = 1110 / 1110

GCD(2, 555) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 602

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

LCM(1, 602) = 602

GCD(1, 602) = ( 1 x 602 ) / 602

GCD(1, 602) = 602 / 602

GCD(1, 602) = 1

GCD of 438, 652, 555, 602 is 1
