Given numbers are 860, 285, 935, 644

The list of prime factors of all numbers are

Prime factors of 860 are 2 x 2 x 5 x 43

Prime factors of 285 are 3 x 5 x 19

Prime factors of 935 are 5 x 11 x 17

Prime factors of 644 are 2 x 2 x 7 x 23

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

Given numbers are 860, 285, 935, 644

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

Apply this formula for all numbers.

Step1:

LCM(860, 285) = 49020

GCD(860, 285) = ( 860 x 285 ) / 49020

= 860 / 285

= 860

Step2:

LCM(5, 935) = 935

GCD(5, 935) = ( 5 x 935 ) / 935

= 5 / 935

= 5

Step3:

LCM(5, 644) = 3220

GCD(5, 644) = ( 5 x 644 ) / 3220

= 5 / 644

= 5

So, Greatest Common Divisor of 860, 285, 935, 644 is 1
