Therefore, GCD of numbers 392, 808, 570, 277 is 1

Given Input Data is 392, 808, 570, 277

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

Prime Factorization of 392 is 2 x 2 x 2 x 7 x 7

Prime Factorization of 808 is 2 x 2 x 2 x 101

Prime Factorization of 570 is 2 x 3 x 5 x 19

Prime Factorization of 277 is 277

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(392, 808) = 39592

GCD(392, 808) = ( 392 x 808 ) / 39592

GCD(392, 808) = 316736 / 39592

GCD(392, 808) = 8

Step2:

Here we consider the GCD from the above i.e. 8 as first number and the next as 570

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

LCM(8, 570) = 2280

GCD(8, 570) = ( 8 x 570 ) / 2280

GCD(8, 570) = 4560 / 2280

GCD(8, 570) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 277

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

LCM(2, 277) = 554

GCD(2, 277) = ( 2 x 277 ) / 554

GCD(2, 277) = 554 / 554

GCD(2, 277) = 1

GCD of 392, 808, 570, 277 is 1
