Therefore, GCD of numbers 18, 942, 130, 671 is 1

Given Input Data is 18, 942, 130, 671

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

Prime Factorization of 18 is 2 x 3 x 3

Prime Factorization of 942 is 2 x 3 x 157

Prime Factorization of 130 is 2 x 5 x 13

Prime Factorization of 671 is 11 x 61

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(18, 942) = 2826

GCD(18, 942) = ( 18 x 942 ) / 2826

GCD(18, 942) = 16956 / 2826

GCD(18, 942) = 6

Step2:

Here we consider the GCD from the above i.e. 6 as first number and the next as 130

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

LCM(6, 130) = 390

GCD(6, 130) = ( 6 x 130 ) / 390

GCD(6, 130) = 780 / 390

GCD(6, 130) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 671

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

LCM(2, 671) = 1342

GCD(2, 671) = ( 2 x 671 ) / 1342

GCD(2, 671) = 1342 / 1342

GCD(2, 671) = 1

GCD of 18, 942, 130, 671 is 1
