Given numbers are 255, 425, 123

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

Apply this formula for all numbers.

Step1:

LCM(255, 425) = 1275

GCD(255, 425) = ( 255 x 425 ) / 1275

= 255 / 425

= 255

Step2:

LCM(85, 123) = 10455

GCD(85, 123) = ( 85 x 123 ) / 10455

= 85 / 123

= 85

So, Greatest Common Divisor of 255, 425, 123 is 1
