Given numbers are 255, 865, 509, 609

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

Apply this formula for all numbers.

Step1:

LCM(255, 865) = 44115

GCD(255, 865) = ( 255 x 865 ) / 44115

= 255 / 865

= 255

Step2:

LCM(5, 509) = 2545

GCD(5, 509) = ( 5 x 509 ) / 2545

= 5 / 509

= 5

Step3:

LCM(1, 609) = 609

GCD(1, 609) = ( 1 x 609 ) / 609

= 1 / 609

= 1

So, Greatest Common Divisor of 255, 865, 509, 609 is 1
