Therefore, GCD of numbers 221, 618, 652 is 1

Given Input Data is 221, 618, 652

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

Prime Factorization of 221 is 13 x 17

Prime Factorization of 618 is 2 x 3 x 103

Prime Factorization of 652 is 2 x 2 x 163

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(221, 618) = 136578

GCD(221, 618) = ( 221 x 618 ) / 136578

GCD(221, 618) = 136578 / 136578

GCD(221, 618) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 652

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

LCM(1, 652) = 652

GCD(1, 652) = ( 1 x 652 ) / 652

GCD(1, 652) = 652 / 652

GCD(1, 652) = 1

GCD of 221, 618, 652 is 1
