Given Input Data is 646, 357, 450, 583

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

Prime Factorization of 646 is 2 x 17 x 19

Prime Factorization of 357 is 3 x 7 x 17

Prime Factorization of 450 is 2 x 3 x 3 x 5 x 5

Prime Factorization of 583 is 11 x 53

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(646, 357) = 13566

GCD(646, 357) = ( 646 x 357 ) / 13566

GCD(646, 357) = 230622 / 13566

GCD(646, 357) = 17

Step2:

Here we consider the GCD from the above i.e. 17 as first number and the next as 450

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

LCM(17, 450) = 7650

GCD(17, 450) = ( 17 x 450 ) / 7650

GCD(17, 450) = 7650 / 7650

GCD(17, 450) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 583

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

LCM(1, 583) = 583

GCD(1, 583) = ( 1 x 583 ) / 583

GCD(1, 583) = 583 / 583

GCD(1, 583) = 1

GCD of 646, 357, 450, 583 is 1
