Therefore, GCD of numbers 728, 128, 879, 195 is 1

Given Input Data is 728, 128, 879, 195

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

Prime Factorization of 728 is 2 x 2 x 2 x 7 x 13

Prime Factorization of 128 is 2 x 2 x 2 x 2 x 2 x 2 x 2

Prime Factorization of 879 is 3 x 293

Prime Factorization of 195 is 3 x 5 x 13

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(728, 128) = 11648

GCD(728, 128) = ( 728 x 128 ) / 11648

GCD(728, 128) = 93184 / 11648

GCD(728, 128) = 8

Step2:

Here we consider the GCD from the above i.e. 8 as first number and the next as 879

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

LCM(8, 879) = 7032

GCD(8, 879) = ( 8 x 879 ) / 7032

GCD(8, 879) = 7032 / 7032

GCD(8, 879) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 195

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

LCM(1, 195) = 195

GCD(1, 195) = ( 1 x 195 ) / 195

GCD(1, 195) = 195 / 195

GCD(1, 195) = 1

GCD of 728, 128, 879, 195 is 1
