Given numbers are 656, 423, 568, 255

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

Apply this formula for all numbers.

Step1:

LCM(656, 423) = 277488

GCD(656, 423) = ( 656 x 423 ) / 277488

= 656 / 423

= 656

Step2:

LCM(1, 568) = 568

GCD(1, 568) = ( 1 x 568 ) / 568

= 1 / 568

= 1

Step3:

LCM(1, 255) = 255

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

= 1 / 255

= 1

So, Greatest Common Divisor of 656, 423, 568, 255 is 1
