Therefore, GCD of numbers 909, 210, 197, 383 is 1

Given Input Data is 909, 210, 197, 383

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 210 is 2 x 3 x 5 x 7

Prime Factorization of 197 is 197

Prime Factorization of 383 is 383

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, 210) = 63630

GCD(909, 210) = ( 909 x 210 ) / 63630

GCD(909, 210) = 190890 / 63630

GCD(909, 210) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 197

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

LCM(3, 197) = 591

GCD(3, 197) = ( 3 x 197 ) / 591

GCD(3, 197) = 591 / 591

GCD(3, 197) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 383

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

LCM(1, 383) = 383

GCD(1, 383) = ( 1 x 383 ) / 383

GCD(1, 383) = 383 / 383

GCD(1, 383) = 1

GCD of 909, 210, 197, 383 is 1
