We found the divisors of 643, 451, 427, 264 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 643, 451, 427, 264 is 1.

Therefore, GCD of numbers 643, 451, 427, 264 is 1

Given Input Data is 643, 451, 427, 264

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

Prime Factorization of 643 is 643

Prime Factorization of 451 is 11 x 41

Prime Factorization of 427 is 7 x 61

Prime Factorization of 264 is 2 x 2 x 2 x 3 x 11

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(643, 451) = 289993

GCD(643, 451) = ( 643 x 451 ) / 289993

GCD(643, 451) = 289993 / 289993

GCD(643, 451) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 427

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

LCM(1, 427) = 427

GCD(1, 427) = ( 1 x 427 ) / 427

GCD(1, 427) = 427 / 427

GCD(1, 427) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 264

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

LCM(1, 264) = 264

GCD(1, 264) = ( 1 x 264 ) / 264

GCD(1, 264) = 264 / 264

GCD(1, 264) = 1

GCD of 643, 451, 427, 264 is 1
