Given numbers are 255, 209, 470, 121

The list of prime factors of all numbers are

Prime factors of 255 are 3 x 5 x 17

Prime factors of 209 are 11 x 19

Prime factors of 470 are 2 x 5 x 47

Prime factors of 121 are 11 x 11

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

Given numbers are 255, 209, 470, 121

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

Apply this formula for all numbers.

Step1:

LCM(255, 209) = 53295

GCD(255, 209) = ( 255 x 209 ) / 53295

= 255 / 209

= 255

Step2:

LCM(1, 470) = 470

GCD(1, 470) = ( 1 x 470 ) / 470

= 1 / 470

= 1

Step3:

LCM(1, 121) = 121

GCD(1, 121) = ( 1 x 121 ) / 121

= 1 / 121

= 1

So, Greatest Common Divisor of 255, 209, 470, 121 is 1
