We found the divisors of 32, 311, 622, 645 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 32, 311, 622, 645 is 1.

Therefore, GCD of numbers 32, 311, 622, 645 is 1

Given Input Data is 32, 311, 622, 645

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

Prime Factorization of 32 is 2 x 2 x 2 x 2 x 2

Prime Factorization of 311 is 311

Prime Factorization of 622 is 2 x 311

Prime Factorization of 645 is 3 x 5 x 43

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(32, 311) = 9952

GCD(32, 311) = ( 32 x 311 ) / 9952

GCD(32, 311) = 9952 / 9952

GCD(32, 311) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 622

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

LCM(1, 622) = 622

GCD(1, 622) = ( 1 x 622 ) / 622

GCD(1, 622) = 622 / 622

GCD(1, 622) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 645

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

LCM(1, 645) = 645

GCD(1, 645) = ( 1 x 645 ) / 645

GCD(1, 645) = 645 / 645

GCD(1, 645) = 1

GCD of 32, 311, 622, 645 is 1
