Therefore, GCD of numbers 904, 678, 181, 490 is 1

Given Input Data is 904, 678, 181, 490

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

Prime Factorization of 904 is 2 x 2 x 2 x 113

Prime Factorization of 678 is 2 x 3 x 113

Prime Factorization of 181 is 181

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

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(904, 678) = 2712

GCD(904, 678) = ( 904 x 678 ) / 2712

GCD(904, 678) = 612912 / 2712

GCD(904, 678) = 226

Step2:

Here we consider the GCD from the above i.e. 226 as first number and the next as 181

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

LCM(226, 181) = 40906

GCD(226, 181) = ( 226 x 181 ) / 40906

GCD(226, 181) = 40906 / 40906

GCD(226, 181) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 490

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

LCM(1, 490) = 490

GCD(1, 490) = ( 1 x 490 ) / 490

GCD(1, 490) = 490 / 490

GCD(1, 490) = 1

GCD of 904, 678, 181, 490 is 1
