Given Input Data is 440, 312, 845, 863

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

Prime Factorization of 440 is 2 x 2 x 2 x 5 x 11

Prime Factorization of 312 is 2 x 2 x 2 x 3 x 13

Prime Factorization of 845 is 5 x 13 x 13

Prime Factorization of 863 is 863

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(440, 312) = 17160

GCD(440, 312) = ( 440 x 312 ) / 17160

GCD(440, 312) = 137280 / 17160

GCD(440, 312) = 8

Step2:

Here we consider the GCD from the above i.e. 8 as first number and the next as 845

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

LCM(8, 845) = 6760

GCD(8, 845) = ( 8 x 845 ) / 6760

GCD(8, 845) = 6760 / 6760

GCD(8, 845) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 863

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

LCM(1, 863) = 863

GCD(1, 863) = ( 1 x 863 ) / 863

GCD(1, 863) = 863 / 863

GCD(1, 863) = 1

GCD of 440, 312, 845, 863 is 1
