Therefore, GCD of numbers 909, 885, 477, 251 is 1

Given Input Data is 909, 885, 477, 251

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

Prime Factorization of 909 is 3 x 3 x 101

Prime Factorization of 885 is 3 x 5 x 59

Prime Factorization of 477 is 3 x 3 x 53

Prime Factorization of 251 is 251

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(909, 885) = 268155

GCD(909, 885) = ( 909 x 885 ) / 268155

GCD(909, 885) = 804465 / 268155

GCD(909, 885) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 477

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

LCM(3, 477) = 477

GCD(3, 477) = ( 3 x 477 ) / 477

GCD(3, 477) = 1431 / 477

GCD(3, 477) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 251

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

LCM(3, 251) = 753

GCD(3, 251) = ( 3 x 251 ) / 753

GCD(3, 251) = 753 / 753

GCD(3, 251) = 1

GCD of 909, 885, 477, 251 is 1
