Given numbers are 523, 688, 423

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

Apply this formula for all numbers.

Step1:

LCM(523, 688) = 359824

GCD(523, 688) = ( 523 x 688 ) / 359824

= 523 / 688

= 523

Step2:

LCM(1, 423) = 423

GCD(1, 423) = ( 1 x 423 ) / 423

= 1 / 423

= 1

So, Greatest Common Divisor of 523, 688, 423 is 1
