Given Input Data is 544, 765, 399

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

Prime Factorization of 544 is 2 x 2 x 2 x 2 x 2 x 17

Prime Factorization of 765 is 3 x 3 x 5 x 17

Prime Factorization of 399 is 3 x 7 x 19

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(544, 765) = 24480

GCD(544, 765) = ( 544 x 765 ) / 24480

GCD(544, 765) = 416160 / 24480

GCD(544, 765) = 17

Step2:

Here we consider the GCD from the above i.e. 17 as first number and the next as 399

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

LCM(17, 399) = 6783

GCD(17, 399) = ( 17 x 399 ) / 6783

GCD(17, 399) = 6783 / 6783

GCD(17, 399) = 1

GCD of 544, 765, 399 is 1
