We found the divisors of 501, 401, 63, 657 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 501, 401, 63, 657 is 1.

Therefore, GCD of numbers 501, 401, 63, 657 is 1

Given Input Data is 501, 401, 63, 657

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

Prime Factorization of 501 is 3 x 167

Prime Factorization of 401 is 401

Prime Factorization of 63 is 3 x 3 x 7

Prime Factorization of 657 is 3 x 3 x 73

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(501, 401) = 200901

GCD(501, 401) = ( 501 x 401 ) / 200901

GCD(501, 401) = 200901 / 200901

GCD(501, 401) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 63

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

LCM(1, 63) = 63

GCD(1, 63) = ( 1 x 63 ) / 63

GCD(1, 63) = 63 / 63

GCD(1, 63) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 657

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

LCM(1, 657) = 657

GCD(1, 657) = ( 1 x 657 ) / 657

GCD(1, 657) = 657 / 657

GCD(1, 657) = 1

GCD of 501, 401, 63, 657 is 1
