Given numbers are 455, 347, 255

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

Apply this formula for all numbers.

Step1:

LCM(455, 347) = 157885

GCD(455, 347) = ( 455 x 347 ) / 157885

= 455 / 347

= 455

Step2:

LCM(1, 255) = 255

GCD(1, 255) = ( 1 x 255 ) / 255

= 1 / 255

= 1

So, Greatest Common Divisor of 455, 347, 255 is 1
