Given Input Data is 845, 660, 12, 419

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

Prime Factorization of 845 is 5 x 13 x 13

Prime Factorization of 660 is 2 x 2 x 3 x 5 x 11

Prime Factorization of 12 is 2 x 2 x 3

Prime Factorization of 419 is 419

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(845, 660) = 111540

GCD(845, 660) = ( 845 x 660 ) / 111540

GCD(845, 660) = 557700 / 111540

GCD(845, 660) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 12

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

LCM(5, 12) = 60

GCD(5, 12) = ( 5 x 12 ) / 60

GCD(5, 12) = 60 / 60

GCD(5, 12) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 419

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

LCM(1, 419) = 419

GCD(1, 419) = ( 1 x 419 ) / 419

GCD(1, 419) = 419 / 419

GCD(1, 419) = 1

GCD of 845, 660, 12, 419 is 1
