Given Input Data is 153, 442, 790

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

Prime Factorization of 153 is 3 x 3 x 17

Prime Factorization of 442 is 2 x 13 x 17

Prime Factorization of 790 is 2 x 5 x 79

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(153, 442) = 3978

GCD(153, 442) = ( 153 x 442 ) / 3978

GCD(153, 442) = 67626 / 3978

GCD(153, 442) = 17

Step2:

Here we consider the GCD from the above i.e. 17 as first number and the next as 790

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

LCM(17, 790) = 13430

GCD(17, 790) = ( 17 x 790 ) / 13430

GCD(17, 790) = 13430 / 13430

GCD(17, 790) = 1

GCD of 153, 442, 790 is 1
