We found the divisors of 771, 232, 245 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 771, 232, 245 is 1.

Therefore, GCD of numbers 771, 232, 245 is 1

Given Input Data is 771, 232, 245

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

Prime Factorization of 771 is 3 x 257

Prime Factorization of 232 is 2 x 2 x 2 x 29

Prime Factorization of 245 is 5 x 7 x 7

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(771, 232) = 178872

GCD(771, 232) = ( 771 x 232 ) / 178872

GCD(771, 232) = 178872 / 178872

GCD(771, 232) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 245

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

LCM(1, 245) = 245

GCD(1, 245) = ( 1 x 245 ) / 245

GCD(1, 245) = 245 / 245

GCD(1, 245) = 1

GCD of 771, 232, 245 is 1
