Therefore, GCD of numbers 730, 805, 668 is 1

Given Input Data is 730, 805, 668

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

Prime Factorization of 730 is 2 x 5 x 73

Prime Factorization of 805 is 5 x 7 x 23

Prime Factorization of 668 is 2 x 2 x 167

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(730, 805) = 117530

GCD(730, 805) = ( 730 x 805 ) / 117530

GCD(730, 805) = 587650 / 117530

GCD(730, 805) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 668

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

LCM(5, 668) = 3340

GCD(5, 668) = ( 5 x 668 ) / 3340

GCD(5, 668) = 3340 / 3340

GCD(5, 668) = 1

GCD of 730, 805, 668 is 1
