Therefore, GCD of numbers 660, 872, 920, 717 is 1

Given Input Data is 660, 872, 920, 717

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

Prime Factorization of 660 is 2 x 2 x 3 x 5 x 11

Prime Factorization of 872 is 2 x 2 x 2 x 109

Prime Factorization of 920 is 2 x 2 x 2 x 5 x 23

Prime Factorization of 717 is 3 x 239

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(660, 872) = 143880

GCD(660, 872) = ( 660 x 872 ) / 143880

GCD(660, 872) = 575520 / 143880

GCD(660, 872) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 920

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

LCM(4, 920) = 920

GCD(4, 920) = ( 4 x 920 ) / 920

GCD(4, 920) = 3680 / 920

GCD(4, 920) = 4

Step3:

Here we consider the GCD from the above i.e. 4 as first number and the next as 717

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

LCM(4, 717) = 2868

GCD(4, 717) = ( 4 x 717 ) / 2868

GCD(4, 717) = 2868 / 2868

GCD(4, 717) = 1

GCD of 660, 872, 920, 717 is 1
