Given Input Data is 749, 392, 631

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

Prime Factorization of 749 is 7 x 107

Prime Factorization of 392 is 2 x 2 x 2 x 7 x 7

Prime Factorization of 631 is 631

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(749, 392) = 41944

GCD(749, 392) = ( 749 x 392 ) / 41944

GCD(749, 392) = 293608 / 41944

GCD(749, 392) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 631

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

LCM(7, 631) = 4417

GCD(7, 631) = ( 7 x 631 ) / 4417

GCD(7, 631) = 4417 / 4417

GCD(7, 631) = 1

GCD of 749, 392, 631 is 1
