We found the divisors of 645, 238, 645, 767 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 645, 238, 645, 767 is 1.

Therefore, GCD of numbers 645, 238, 645, 767 is 1

Given Input Data is 645, 238, 645, 767

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

Prime Factorization of 645 is 3 x 5 x 43

Prime Factorization of 238 is 2 x 7 x 17

Prime Factorization of 645 is 3 x 5 x 43

Prime Factorization of 767 is 13 x 59

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(645, 238) = 153510

GCD(645, 238) = ( 645 x 238 ) / 153510

GCD(645, 238) = 153510 / 153510

GCD(645, 238) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 645

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

LCM(1, 645) = 645

GCD(1, 645) = ( 1 x 645 ) / 645

GCD(1, 645) = 645 / 645

GCD(1, 645) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 767

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

LCM(1, 767) = 767

GCD(1, 767) = ( 1 x 767 ) / 767

GCD(1, 767) = 767 / 767

GCD(1, 767) = 1

GCD of 645, 238, 645, 767 is 1
