Given numbers are 765, 445, 612, 855

The list of prime factors of all numbers are

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

Prime factors of 445 are 5 x 89

Prime factors of 612 are 2 x 2 x 3 x 3 x 17

Prime factors of 855 are 3 x 3 x 5 x 19

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

Given numbers are 765, 445, 612, 855

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

Apply this formula for all numbers.

Step1:

LCM(765, 445) = 68085

GCD(765, 445) = ( 765 x 445 ) / 68085

= 765 / 445

= 765

Step2:

LCM(5, 612) = 3060

GCD(5, 612) = ( 5 x 612 ) / 3060

= 5 / 612

= 5

Step3:

LCM(1, 855) = 855

GCD(1, 855) = ( 1 x 855 ) / 855

= 1 / 855

= 1

So, Greatest Common Divisor of 765, 445, 612, 855 is 1
