Given numbers are 255, 745, 191, 558

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

Apply this formula for all numbers.

Step1:

LCM(255, 745) = 37995

GCD(255, 745) = ( 255 x 745 ) / 37995

= 255 / 745

= 255

Step2:

LCM(5, 191) = 955

GCD(5, 191) = ( 5 x 191 ) / 955

= 5 / 191

= 5

Step3:

LCM(1, 558) = 558

GCD(1, 558) = ( 1 x 558 ) / 558

= 1 / 558

= 1

So, Greatest Common Divisor of 255, 745, 191, 558 is 1
