Given numbers are 285, 646, 191, 250

The list of prime factors of all numbers are

Prime factors of 285 are 3 x 5 x 19

Prime factors of 646 are 2 x 17 x 19

Prime factors of 191 are 191

Prime factors of 250 are 2 x 5 x 5 x 5

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

Given numbers are 285, 646, 191, 250

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

Apply this formula for all numbers.

Step1:

LCM(285, 646) = 9690

GCD(285, 646) = ( 285 x 646 ) / 9690

= 285 / 646

= 285

Step2:

LCM(19, 191) = 3629

GCD(19, 191) = ( 19 x 191 ) / 3629

= 19 / 191

= 19

Step3:

LCM(1, 250) = 250

GCD(1, 250) = ( 1 x 250 ) / 250

= 1 / 250

= 1

So, Greatest Common Divisor of 285, 646, 191, 250 is 1
