The list of prime factors of all numbers are

Prime factors of 865 are 5 x 173

Prime factors of 611 are 13 x 47

Prime factors of 444 are 2 x 2 x 3 x 37

Prime factors of 321 are 3 x 107

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

Given numbers are 865, 611, 444, 321

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

Apply this formula for all numbers.

Step1:

LCM(865, 611) = 528515

GCD(865, 611) = ( 865 x 611 ) / 528515

= 865 / 611

= 865

Step2:

LCM(1, 444) = 444

GCD(1, 444) = ( 1 x 444 ) / 444

= 1 / 444

= 1

Step3:

LCM(1, 321) = 321

GCD(1, 321) = ( 1 x 321 ) / 321

= 1 / 321

= 1

So, Greatest Common Divisor of 865, 611, 444, 321 is 1
