Given numbers are 285, 422, 763, 321

The list of prime factors of all numbers are

Prime factors of 285 are 3 x 5 x 19

Prime factors of 422 are 2 x 211

Prime factors of 763 are 7 x 109

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 285, 422, 763, 321

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

Apply this formula for all numbers.

Step1:

LCM(285, 422) = 120270

GCD(285, 422) = ( 285 x 422 ) / 120270

= 285 / 422

= 285

Step2:

LCM(1, 763) = 763

GCD(1, 763) = ( 1 x 763 ) / 763

= 1 / 763

= 1

Step3:

LCM(1, 321) = 321

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

= 1 / 321

= 1

So, Greatest Common Divisor of 285, 422, 763, 321 is 1
