Therefore, GCD of numbers 198, 771, 263, 908 is 1

Given Input Data is 198, 771, 263, 908

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

Prime Factorization of 198 is 2 x 3 x 3 x 11

Prime Factorization of 771 is 3 x 257

Prime Factorization of 263 is 263

Prime Factorization of 908 is 2 x 2 x 227

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(198, 771) = 50886

GCD(198, 771) = ( 198 x 771 ) / 50886

GCD(198, 771) = 152658 / 50886

GCD(198, 771) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 263

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

LCM(3, 263) = 789

GCD(3, 263) = ( 3 x 263 ) / 789

GCD(3, 263) = 789 / 789

GCD(3, 263) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 908

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

LCM(1, 908) = 908

GCD(1, 908) = ( 1 x 908 ) / 908

GCD(1, 908) = 908 / 908

GCD(1, 908) = 1

GCD of 198, 771, 263, 908 is 1
