We found the divisors of 530, 250, 247, 654 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 530, 250, 247, 654 is 1.

Therefore, GCD of numbers 530, 250, 247, 654 is 1

Given Input Data is 530, 250, 247, 654

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 250 is 2 x 5 x 5 x 5

Prime Factorization of 247 is 13 x 19

Prime Factorization of 654 is 2 x 3 x 109

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, 250) = 13250

GCD(530, 250) = ( 530 x 250 ) / 13250

GCD(530, 250) = 132500 / 13250

GCD(530, 250) = 10

Step2:

Here we consider the GCD from the above i.e. 10 as first number and the next as 247

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

LCM(10, 247) = 2470

GCD(10, 247) = ( 10 x 247 ) / 2470

GCD(10, 247) = 2470 / 2470

GCD(10, 247) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 654

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

LCM(1, 654) = 654

GCD(1, 654) = ( 1 x 654 ) / 654

GCD(1, 654) = 654 / 654

GCD(1, 654) = 1

GCD of 530, 250, 247, 654 is 1
