Therefore, GCD of numbers 888, 128, 813, 385 is 1

Given Input Data is 888, 128, 813, 385

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

Prime Factorization of 888 is 2 x 2 x 2 x 3 x 37

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

Prime Factorization of 813 is 3 x 271

Prime Factorization of 385 is 5 x 7 x 11

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(888, 128) = 14208

GCD(888, 128) = ( 888 x 128 ) / 14208

GCD(888, 128) = 113664 / 14208

GCD(888, 128) = 8

Step2:

Here we consider the GCD from the above i.e. 8 as first number and the next as 813

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

LCM(8, 813) = 6504

GCD(8, 813) = ( 8 x 813 ) / 6504

GCD(8, 813) = 6504 / 6504

GCD(8, 813) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 385

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

LCM(1, 385) = 385

GCD(1, 385) = ( 1 x 385 ) / 385

GCD(1, 385) = 385 / 385

GCD(1, 385) = 1

GCD of 888, 128, 813, 385 is 1
