Therefore, GCD of numbers 355, 195, 528, 668 is 1

Given Input Data is 355, 195, 528, 668

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

Prime Factorization of 355 is 5 x 71

Prime Factorization of 195 is 3 x 5 x 13

Prime Factorization of 528 is 2 x 2 x 2 x 2 x 3 x 11

Prime Factorization of 668 is 2 x 2 x 167

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(355, 195) = 13845

GCD(355, 195) = ( 355 x 195 ) / 13845

GCD(355, 195) = 69225 / 13845

GCD(355, 195) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 528

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

LCM(5, 528) = 2640

GCD(5, 528) = ( 5 x 528 ) / 2640

GCD(5, 528) = 2640 / 2640

GCD(5, 528) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 668

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

LCM(1, 668) = 668

GCD(1, 668) = ( 1 x 668 ) / 668

GCD(1, 668) = 668 / 668

GCD(1, 668) = 1

GCD of 355, 195, 528, 668 is 1
