Given numbers are 765, 435, 180, 809

The list of prime factors of all numbers are

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

Prime factors of 435 are 3 x 5 x 29

Prime factors of 180 are 2 x 2 x 3 x 3 x 5

Prime factors of 809 are 809

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

Given numbers are 765, 435, 180, 809

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

Apply this formula for all numbers.

Step1:

LCM(765, 435) = 22185

GCD(765, 435) = ( 765 x 435 ) / 22185

= 765 / 435

= 765

Step2:

LCM(15, 180) = 180

GCD(15, 180) = ( 15 x 180 ) / 180

= 15 / 180

= 15

Step3:

LCM(15, 809) = 12135

GCD(15, 809) = ( 15 x 809 ) / 12135

= 15 / 809

= 15

So, Greatest Common Divisor of 765, 435, 180, 809 is 1
