Therefore, GCD of numbers 198, 621, 13, 907 is 1

Given Input Data is 198, 621, 13, 907

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

Prime Factorization of 198 is 2 x 3 x 3 x 11

Prime Factorization of 621 is 3 x 3 x 3 x 23

Prime Factorization of 13 is 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(198, 621) = 13662

GCD(198, 621) = ( 198 x 621 ) / 13662

GCD(198, 621) = 122958 / 13662

GCD(198, 621) = 9

Step2:

Here we consider the GCD from the above i.e. 9 as first number and the next as 13

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

LCM(9, 13) = 117

GCD(9, 13) = ( 9 x 13 ) / 117

GCD(9, 13) = 117 / 117

GCD(9, 13) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 907

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

LCM(1, 907) = 907

GCD(1, 907) = ( 1 x 907 ) / 907

GCD(1, 907) = 907 / 907

GCD(1, 907) = 1

GCD of 198, 621, 13, 907 is 1
