Therefore, GCD of numbers 190, 656, 81 is 1

Given Input Data is 190, 656, 81

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

Prime Factorization of 190 is 2 x 5 x 19

Prime Factorization of 656 is 2 x 2 x 2 x 2 x 41

Prime Factorization of 81 is 3 x 3 x 3 x 3

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(190, 656) = 62320

GCD(190, 656) = ( 190 x 656 ) / 62320

GCD(190, 656) = 124640 / 62320

GCD(190, 656) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 81

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

LCM(2, 81) = 162

GCD(2, 81) = ( 2 x 81 ) / 162

GCD(2, 81) = 162 / 162

GCD(2, 81) = 1

GCD of 190, 656, 81 is 1
