So the Greatest Common Divisior 711, 645, 305, 325 is 1.

Therefore, GCD of numbers 711, 645, 305, 325 is 1

Given Input Data is 711, 645, 305, 325

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

Prime Factorization of 711 is 3 x 3 x 79

Prime Factorization of 645 is 3 x 5 x 43

Prime Factorization of 305 is 5 x 61

Prime Factorization of 325 is 5 x 5 x 13

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(711, 645) = 152865

GCD(711, 645) = ( 711 x 645 ) / 152865

GCD(711, 645) = 458595 / 152865

GCD(711, 645) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 305

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

LCM(3, 305) = 915

GCD(3, 305) = ( 3 x 305 ) / 915

GCD(3, 305) = 915 / 915

GCD(3, 305) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 325

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

LCM(1, 325) = 325

GCD(1, 325) = ( 1 x 325 ) / 325

GCD(1, 325) = 325 / 325

GCD(1, 325) = 1

GCD of 711, 645, 305, 325 is 1
