Given Input Data is 468, 153, 85, 665

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

Prime Factorization of 468 is 2 x 2 x 3 x 3 x 13

Prime Factorization of 153 is 3 x 3 x 17

Prime Factorization of 85 is 5 x 17

Prime Factorization of 665 is 5 x 7 x 19

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(468, 153) = 7956

GCD(468, 153) = ( 468 x 153 ) / 7956

GCD(468, 153) = 71604 / 7956

GCD(468, 153) = 9

Step2:

Here we consider the GCD from the above i.e. 9 as first number and the next as 85

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

LCM(9, 85) = 765

GCD(9, 85) = ( 9 x 85 ) / 765

GCD(9, 85) = 765 / 765

GCD(9, 85) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 665

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

LCM(1, 665) = 665

GCD(1, 665) = ( 1 x 665 ) / 665

GCD(1, 665) = 665 / 665

GCD(1, 665) = 1

GCD of 468, 153, 85, 665 is 1
