Given numbers are 810, 865, 604, 728

The list of prime factors of all numbers are

Prime factors of 810 are 2 x 3 x 3 x 3 x 3 x 5

Prime factors of 865 are 5 x 173

Prime factors of 604 are 2 x 2 x 151

Prime factors of 728 are 2 x 2 x 2 x 7 x 13

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

Given numbers are 810, 865, 604, 728

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

Apply this formula for all numbers.

Step1:

LCM(810, 865) = 140130

GCD(810, 865) = ( 810 x 865 ) / 140130

= 810 / 865

= 810

Step2:

LCM(5, 604) = 3020

GCD(5, 604) = ( 5 x 604 ) / 3020

= 5 / 604

= 5

Step3:

LCM(1, 728) = 728

GCD(1, 728) = ( 1 x 728 ) / 728

= 1 / 728

= 1

So, Greatest Common Divisor of 810, 865, 604, 728 is 1
