We found the divisors of 130, 247, 333, 628 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 130, 247, 333, 628 is 1.

Therefore, GCD of numbers 130, 247, 333, 628 is 1

Given Input Data is 130, 247, 333, 628

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

Prime Factorization of 130 is 2 x 5 x 13

Prime Factorization of 247 is 13 x 19

Prime Factorization of 333 is 3 x 3 x 37

Prime Factorization of 628 is 2 x 2 x 157

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(130, 247) = 2470

GCD(130, 247) = ( 130 x 247 ) / 2470

GCD(130, 247) = 32110 / 2470

GCD(130, 247) = 13

Step2:

Here we consider the GCD from the above i.e. 13 as first number and the next as 333

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

LCM(13, 333) = 4329

GCD(13, 333) = ( 13 x 333 ) / 4329

GCD(13, 333) = 4329 / 4329

GCD(13, 333) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 628

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

LCM(1, 628) = 628

GCD(1, 628) = ( 1 x 628 ) / 628

GCD(1, 628) = 628 / 628

GCD(1, 628) = 1

GCD of 130, 247, 333, 628 is 1
