Therefore, GCD of numbers 490, 168, 27, 472 is 1

Given Input Data is 490, 168, 27, 472

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 168 is 2 x 2 x 2 x 3 x 7

Prime Factorization of 27 is 3 x 3 x 3

Prime Factorization of 472 is 2 x 2 x 2 x 59

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, 168) = 5880

GCD(490, 168) = ( 490 x 168 ) / 5880

GCD(490, 168) = 82320 / 5880

GCD(490, 168) = 14

Step2:

Here we consider the GCD from the above i.e. 14 as first number and the next as 27

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

LCM(14, 27) = 378

GCD(14, 27) = ( 14 x 27 ) / 378

GCD(14, 27) = 378 / 378

GCD(14, 27) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 472

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

LCM(1, 472) = 472

GCD(1, 472) = ( 1 x 472 ) / 472

GCD(1, 472) = 472 / 472

GCD(1, 472) = 1

GCD of 490, 168, 27, 472 is 1
