Therefore, GCD of numbers 805, 695, 212 is 1

Given Input Data is 805, 695, 212

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

Prime Factorization of 805 is 5 x 7 x 23

Prime Factorization of 695 is 5 x 139

Prime Factorization of 212 is 2 x 2 x 53

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(805, 695) = 111895

GCD(805, 695) = ( 805 x 695 ) / 111895

GCD(805, 695) = 559475 / 111895

GCD(805, 695) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 212

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

LCM(5, 212) = 1060

GCD(5, 212) = ( 5 x 212 ) / 1060

GCD(5, 212) = 1060 / 1060

GCD(5, 212) = 1

GCD of 805, 695, 212 is 1
