Given Input Data is 715, 260, 578

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

Prime Factorization of 715 is 5 x 11 x 13

Prime Factorization of 260 is 2 x 2 x 5 x 13

Prime Factorization of 578 is 2 x 17 x 17

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(715, 260) = 2860

GCD(715, 260) = ( 715 x 260 ) / 2860

GCD(715, 260) = 185900 / 2860

GCD(715, 260) = 65

Step2:

Here we consider the GCD from the above i.e. 65 as first number and the next as 578

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

LCM(65, 578) = 37570

GCD(65, 578) = ( 65 x 578 ) / 37570

GCD(65, 578) = 37570 / 37570

GCD(65, 578) = 1

GCD of 715, 260, 578 is 1
