We found the divisors of 519, 251, 693, 247 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 519, 251, 693, 247 is 1.

Therefore, GCD of numbers 519, 251, 693, 247 is 1

Given Input Data is 519, 251, 693, 247

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

Prime Factorization of 519 is 3 x 173

Prime Factorization of 251 is 251

Prime Factorization of 693 is 3 x 3 x 7 x 11

Prime Factorization of 247 is 13 x 19

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(519, 251) = 130269

GCD(519, 251) = ( 519 x 251 ) / 130269

GCD(519, 251) = 130269 / 130269

GCD(519, 251) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 693

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

LCM(1, 693) = 693

GCD(1, 693) = ( 1 x 693 ) / 693

GCD(1, 693) = 693 / 693

GCD(1, 693) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 247

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

LCM(1, 247) = 247

GCD(1, 247) = ( 1 x 247 ) / 247

GCD(1, 247) = 247 / 247

GCD(1, 247) = 1

GCD of 519, 251, 693, 247 is 1
