Given numbers are 765, 894, 808, 687

The list of prime factors of all numbers are

Prime factors of 765 are 3 x 3 x 5 x 17

Prime factors of 894 are 2 x 3 x 149

Prime factors of 808 are 2 x 2 x 2 x 101

Prime factors of 687 are 3 x 229

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 765, 894, 808, 687

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(765, 894) = 227970

GCD(765, 894) = ( 765 x 894 ) / 227970

= 765 / 894

= 765

Step2:

LCM(3, 808) = 2424

GCD(3, 808) = ( 3 x 808 ) / 2424

= 3 / 808

= 3

Step3:

LCM(1, 687) = 687

GCD(1, 687) = ( 1 x 687 ) / 687

= 1 / 687

= 1

So, Greatest Common Divisor of 765, 894, 808, 687 is 1
