We found the divisors of 421, 303, 773, 210 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 421, 303, 773, 210 is 1.

Therefore, GCD of numbers 421, 303, 773, 210 is 1

Given Input Data is 421, 303, 773, 210

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

Prime Factorization of 421 is 421

Prime Factorization of 303 is 3 x 101

Prime Factorization of 773 is 773

Prime Factorization of 210 is 2 x 3 x 5 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(421, 303) = 127563

GCD(421, 303) = ( 421 x 303 ) / 127563

GCD(421, 303) = 127563 / 127563

GCD(421, 303) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 773

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

LCM(1, 773) = 773

GCD(1, 773) = ( 1 x 773 ) / 773

GCD(1, 773) = 773 / 773

GCD(1, 773) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 210

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

LCM(1, 210) = 210

GCD(1, 210) = ( 1 x 210 ) / 210

GCD(1, 210) = 210 / 210

GCD(1, 210) = 1

GCD of 421, 303, 773, 210 is 1
