Given numbers are 255, 861, 791, 874

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

Apply this formula for all numbers.

Step1:

LCM(255, 861) = 73185

GCD(255, 861) = ( 255 x 861 ) / 73185

= 255 / 861

= 255

Step2:

LCM(3, 791) = 2373

GCD(3, 791) = ( 3 x 791 ) / 2373

= 3 / 791

= 3

Step3:

LCM(1, 874) = 874

GCD(1, 874) = ( 1 x 874 ) / 874

= 1 / 874

= 1

So, Greatest Common Divisor of 255, 861, 791, 874 is 1
