We found the divisors of 530, 251, 553, 533 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 530, 251, 553, 533 is 1.

Therefore, GCD of numbers 530, 251, 553, 533 is 1

Given Input Data is 530, 251, 553, 533

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

Prime Factorization of 530 is 2 x 5 x 53

Prime Factorization of 251 is 251

Prime Factorization of 553 is 7 x 79

Prime Factorization of 533 is 13 x 41

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(530, 251) = 133030

GCD(530, 251) = ( 530 x 251 ) / 133030

GCD(530, 251) = 133030 / 133030

GCD(530, 251) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 553

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

LCM(1, 553) = 553

GCD(1, 553) = ( 1 x 553 ) / 553

GCD(1, 553) = 553 / 553

GCD(1, 553) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 533

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

LCM(1, 533) = 533

GCD(1, 533) = ( 1 x 533 ) / 533

GCD(1, 533) = 533 / 533

GCD(1, 533) = 1

GCD of 530, 251, 553, 533 is 1
