We found the divisors of 301, 161, 644, 517 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 301, 161, 644, 517 is 1.

Therefore, GCD of numbers 301, 161, 644, 517 is 1

Given Input Data is 301, 161, 644, 517

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

Prime Factorization of 301 is 7 x 43

Prime Factorization of 161 is 7 x 23

Prime Factorization of 644 is 2 x 2 x 7 x 23

Prime Factorization of 517 is 11 x 47

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(301, 161) = 6923

GCD(301, 161) = ( 301 x 161 ) / 6923

GCD(301, 161) = 48461 / 6923

GCD(301, 161) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 644

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

LCM(7, 644) = 644

GCD(7, 644) = ( 7 x 644 ) / 644

GCD(7, 644) = 4508 / 644

GCD(7, 644) = 7

Step3:

Here we consider the GCD from the above i.e. 7 as first number and the next as 517

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

LCM(7, 517) = 3619

GCD(7, 517) = ( 7 x 517 ) / 3619

GCD(7, 517) = 3619 / 3619

GCD(7, 517) = 1

GCD of 301, 161, 644, 517 is 1
