Therefore, GCD of numbers 765, 237, 770, 778 is 1

Given Input Data is 765, 237, 770, 778

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

Prime Factorization of 765 is 3 x 3 x 5 x 17

Prime Factorization of 237 is 3 x 79

Prime Factorization of 770 is 2 x 5 x 7 x 11

Prime Factorization of 778 is 2 x 389

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(765, 237) = 60435

GCD(765, 237) = ( 765 x 237 ) / 60435

GCD(765, 237) = 181305 / 60435

GCD(765, 237) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 770

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

LCM(3, 770) = 2310

GCD(3, 770) = ( 3 x 770 ) / 2310

GCD(3, 770) = 2310 / 2310

GCD(3, 770) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 778

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

LCM(1, 778) = 778

GCD(1, 778) = ( 1 x 778 ) / 778

GCD(1, 778) = 778 / 778

GCD(1, 778) = 1

GCD of 765, 237, 770, 778 is 1
