Therefore, GCD of numbers 628, 706, 582, 247 is 1

Given Input Data is 628, 706, 582, 247

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

Prime Factorization of 628 is 2 x 2 x 157

Prime Factorization of 706 is 2 x 353

Prime Factorization of 582 is 2 x 3 x 97

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(628, 706) = 221684

GCD(628, 706) = ( 628 x 706 ) / 221684

GCD(628, 706) = 443368 / 221684

GCD(628, 706) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 582

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

LCM(2, 582) = 582

GCD(2, 582) = ( 2 x 582 ) / 582

GCD(2, 582) = 1164 / 582

GCD(2, 582) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 247

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

LCM(2, 247) = 494

GCD(2, 247) = ( 2 x 247 ) / 494

GCD(2, 247) = 494 / 494

GCD(2, 247) = 1

GCD of 628, 706, 582, 247 is 1
