Given Input Data is 640, 912, 818, 719

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

Prime Factorization of 640 is 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

Prime Factorization of 912 is 2 x 2 x 2 x 2 x 3 x 19

Prime Factorization of 818 is 2 x 409

Prime Factorization of 719 is 719

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(640, 912) = 36480

GCD(640, 912) = ( 640 x 912 ) / 36480

GCD(640, 912) = 583680 / 36480

GCD(640, 912) = 16

Step2:

Here we consider the GCD from the above i.e. 16 as first number and the next as 818

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

LCM(16, 818) = 6544

GCD(16, 818) = ( 16 x 818 ) / 6544

GCD(16, 818) = 13088 / 6544

GCD(16, 818) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 719

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

LCM(2, 719) = 1438

GCD(2, 719) = ( 2 x 719 ) / 1438

GCD(2, 719) = 1438 / 1438

GCD(2, 719) = 1

GCD of 640, 912, 818, 719 is 1
