Given numbers are 865, 331, 816, 903

The list of prime factors of all numbers are

Prime factors of 865 are 5 x 173

Prime factors of 331 are 331

Prime factors of 816 are 2 x 2 x 2 x 2 x 3 x 17

Prime factors of 903 are 3 x 7 x 43

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

Given numbers are 865, 331, 816, 903

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

Apply this formula for all numbers.

Step1:

LCM(865, 331) = 286315

GCD(865, 331) = ( 865 x 331 ) / 286315

= 865 / 331

= 865

Step2:

LCM(1, 816) = 816

GCD(1, 816) = ( 1 x 816 ) / 816

= 1 / 816

= 1

Step3:

LCM(1, 903) = 903

GCD(1, 903) = ( 1 x 903 ) / 903

= 1 / 903

= 1

So, Greatest Common Divisor of 865, 331, 816, 903 is 1
