Greatest Common Divisior

We found the divisors of 421, 253, 836, 604 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 421, 253, 836, 604 is 1.

Therefore, GCD of numbers 421, 253, 836, 604 is 1

Given Input Data is 421, 253, 836, 604

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

Prime Factorization of 421 is 421

Prime Factorization of 253 is 11 x 23

Prime Factorization of 836 is 2 x 2 x 11 x 19

Prime Factorization of 604 is 2 x 2 x 151

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, 253) = 106513

GCD(421, 253) = ( 421 x 253 ) / 106513

GCD(421, 253) = 106513 / 106513

GCD(421, 253) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 836

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

LCM(1, 836) = 836

GCD(1, 836) = ( 1 x 836 ) / 836

GCD(1, 836) = 836 / 836

GCD(1, 836) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 604

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

LCM(1, 604) = 604

GCD(1, 604) = ( 1 x 604 ) / 604

GCD(1, 604) = 604 / 604

GCD(1, 604) = 1

GCD of 421, 253, 836, 604 is 1
