Given numbers are 255, 173, 210, 666

The list of prime factors of all numbers are

Prime factors of 255 are 3 x 5 x 17

Prime factors of 173 are 173

Prime factors of 210 are 2 x 3 x 5 x 7

Prime factors of 666 are 2 x 3 x 3 x 37

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

Given numbers are 255, 173, 210, 666

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

Apply this formula for all numbers.

Step1:

LCM(255, 173) = 44115

GCD(255, 173) = ( 255 x 173 ) / 44115

= 255 / 173

= 255

Step2:

LCM(1, 210) = 210

GCD(1, 210) = ( 1 x 210 ) / 210

= 1 / 210

= 1

Step3:

LCM(1, 666) = 666

GCD(1, 666) = ( 1 x 666 ) / 666

= 1 / 666

= 1

So, Greatest Common Divisor of 255, 173, 210, 666 is 1
