Given numbers are 321, 356, 847, 285

The list of prime factors of all numbers are

Prime factors of 321 are 3 x 107

Prime factors of 356 are 2 x 2 x 89

Prime factors of 847 are 7 x 11 x 11

Prime factors of 285 are 3 x 5 x 19

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

Given numbers are 321, 356, 847, 285

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

Apply this formula for all numbers.

Step1:

LCM(321, 356) = 114276

GCD(321, 356) = ( 321 x 356 ) / 114276

= 321 / 356

= 321

Step2:

LCM(1, 847) = 847

GCD(1, 847) = ( 1 x 847 ) / 847

= 1 / 847

= 1

Step3:

LCM(1, 285) = 285

GCD(1, 285) = ( 1 x 285 ) / 285

= 1 / 285

= 1

So, Greatest Common Divisor of 321, 356, 847, 285 is 1
