Given numbers are 646, 856, 500, 285

The list of prime factors of all numbers are

Prime factors of 646 are 2 x 17 x 19

Prime factors of 856 are 2 x 2 x 2 x 107

Prime factors of 500 are 2 x 2 x 5 x 5 x 5

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 646, 856, 500, 285

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

Apply this formula for all numbers.

Step1:

LCM(646, 856) = 276488

GCD(646, 856) = ( 646 x 856 ) / 276488

= 646 / 856

= 646

Step2:

LCM(2, 500) = 500

GCD(2, 500) = ( 2 x 500 ) / 500

= 2 / 500

= 2

Step3:

LCM(2, 285) = 570

GCD(2, 285) = ( 2 x 285 ) / 570

= 2 / 285

= 2

So, Greatest Common Divisor of 646, 856, 500, 285 is 1
