Given numbers are 426, 255, 991

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

Apply this formula for all numbers.

Step1:

LCM(426, 255) = 36210

GCD(426, 255) = ( 426 x 255 ) / 36210

= 426 / 255

= 426

Step2:

LCM(3, 991) = 2973

GCD(3, 991) = ( 3 x 991 ) / 2973

= 3 / 991

= 3

So, Greatest Common Divisor of 426, 255, 991 is 1
