Given numbers are 255, 986, 811, 449

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

Apply this formula for all numbers.

Step1:

LCM(255, 986) = 14790

GCD(255, 986) = ( 255 x 986 ) / 14790

= 255 / 986

= 255

Step2:

LCM(17, 811) = 13787

GCD(17, 811) = ( 17 x 811 ) / 13787

= 17 / 811

= 17

Step3:

LCM(1, 449) = 449

GCD(1, 449) = ( 1 x 449 ) / 449

= 1 / 449

= 1

So, Greatest Common Divisor of 255, 986, 811, 449 is 1
