Given numbers are 285, 920, 255, 671

The list of prime factors of all numbers are

Prime factors of 285 are 3 x 5 x 19

Prime factors of 920 are 2 x 2 x 2 x 5 x 23

Prime factors of 255 are 3 x 5 x 17

Prime factors of 671 are 11 x 61

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

Given numbers are 285, 920, 255, 671

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

Apply this formula for all numbers.

Step1:

LCM(285, 920) = 52440

GCD(285, 920) = ( 285 x 920 ) / 52440

= 285 / 920

= 285

Step2:

LCM(5, 255) = 255

GCD(5, 255) = ( 5 x 255 ) / 255

= 5 / 255

= 5

Step3:

LCM(5, 671) = 3355

GCD(5, 671) = ( 5 x 671 ) / 3355

= 5 / 671

= 5

So, Greatest Common Divisor of 285, 920, 255, 671 is 1
