We found the divisors of 431, 332, 637, 440 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 431, 332, 637, 440 is 1.

Therefore, GCD of numbers 431, 332, 637, 440 is 1

Given Input Data is 431, 332, 637, 440

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

Prime Factorization of 431 is 431

Prime Factorization of 332 is 2 x 2 x 83

Prime Factorization of 637 is 7 x 7 x 13

Prime Factorization of 440 is 2 x 2 x 2 x 5 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(431, 332) = 143092

GCD(431, 332) = ( 431 x 332 ) / 143092

GCD(431, 332) = 143092 / 143092

GCD(431, 332) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 637

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

LCM(1, 637) = 637

GCD(1, 637) = ( 1 x 637 ) / 637

GCD(1, 637) = 637 / 637

GCD(1, 637) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 440

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

LCM(1, 440) = 440

GCD(1, 440) = ( 1 x 440 ) / 440

GCD(1, 440) = 440 / 440

GCD(1, 440) = 1

GCD of 431, 332, 637, 440 is 1
