Given Input Data is 770, 645, 897

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

Prime Factorization of 770 is 2 x 5 x 7 x 11

Prime Factorization of 645 is 3 x 5 x 43

Prime Factorization of 897 is 3 x 13 x 23

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(770, 645) = 99330

GCD(770, 645) = ( 770 x 645 ) / 99330

GCD(770, 645) = 496650 / 99330

GCD(770, 645) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 897

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

LCM(5, 897) = 4485

GCD(5, 897) = ( 5 x 897 ) / 4485

GCD(5, 897) = 4485 / 4485

GCD(5, 897) = 1

GCD of 770, 645, 897 is 1
