Given numbers are 210, 105, 309, 255

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

Apply this formula for all numbers.

Step1:

LCM(210, 105) = 210

GCD(210, 105) = ( 210 x 105 ) / 210

= 210 / 105

= 210

Step2:

LCM(105, 309) = 10815

GCD(105, 309) = ( 105 x 309 ) / 10815

= 105 / 309

= 105

Step3:

LCM(3, 255) = 255

GCD(3, 255) = ( 3 x 255 ) / 255

= 3 / 255

= 3

So, Greatest Common Divisor of 210, 105, 309, 255 is 3
