Given Input Data is 375, 561, 277, 392

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

Prime Factorization of 375 is 3 x 5 x 5 x 5

Prime Factorization of 561 is 3 x 11 x 17

Prime Factorization of 277 is 277

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

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(375, 561) = 70125

GCD(375, 561) = ( 375 x 561 ) / 70125

GCD(375, 561) = 210375 / 70125

GCD(375, 561) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 277

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

LCM(3, 277) = 831

GCD(3, 277) = ( 3 x 277 ) / 831

GCD(3, 277) = 831 / 831

GCD(3, 277) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 392

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

LCM(1, 392) = 392

GCD(1, 392) = ( 1 x 392 ) / 392

GCD(1, 392) = 392 / 392

GCD(1, 392) = 1

GCD of 375, 561, 277, 392 is 1
