Therefore, GCD of numbers 481, 417, 91, 990 is 1

Given Input Data is 481, 417, 91, 990

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

Prime Factorization of 481 is 13 x 37

Prime Factorization of 417 is 3 x 139

Prime Factorization of 91 is 7 x 13

Prime Factorization of 990 is 2 x 3 x 3 x 5 x 11

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(481, 417) = 200577

GCD(481, 417) = ( 481 x 417 ) / 200577

GCD(481, 417) = 200577 / 200577

GCD(481, 417) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 91

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

LCM(1, 91) = 91

GCD(1, 91) = ( 1 x 91 ) / 91

GCD(1, 91) = 91 / 91

GCD(1, 91) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 990

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

LCM(1, 990) = 990

GCD(1, 990) = ( 1 x 990 ) / 990

GCD(1, 990) = 990 / 990

GCD(1, 990) = 1

GCD of 481, 417, 91, 990 is 1
