Therefore, GCD of numbers 490, 171, 303 is 1

Given Input Data is 490, 171, 303

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

Prime Factorization of 490 is 2 x 5 x 7 x 7

Prime Factorization of 171 is 3 x 3 x 19

Prime Factorization of 303 is 3 x 101

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(490, 171) = 83790

GCD(490, 171) = ( 490 x 171 ) / 83790

GCD(490, 171) = 83790 / 83790

GCD(490, 171) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 303

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

LCM(1, 303) = 303

GCD(1, 303) = ( 1 x 303 ) / 303

GCD(1, 303) = 303 / 303

GCD(1, 303) = 1

GCD of 490, 171, 303 is 1
