Given Input Data is 183, 561, 390, 907

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

Prime Factorization of 183 is 3 x 61

Prime Factorization of 561 is 3 x 11 x 17

Prime Factorization of 390 is 2 x 3 x 5 x 13

Prime Factorization of 907 is 907

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(183, 561) = 34221

GCD(183, 561) = ( 183 x 561 ) / 34221

GCD(183, 561) = 102663 / 34221

GCD(183, 561) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 390

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

LCM(3, 390) = 390

GCD(3, 390) = ( 3 x 390 ) / 390

GCD(3, 390) = 1170 / 390

GCD(3, 390) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 907

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

LCM(3, 907) = 2721

GCD(3, 907) = ( 3 x 907 ) / 2721

GCD(3, 907) = 2721 / 2721

GCD(3, 907) = 1

GCD of 183, 561, 390, 907 is 1
