Given numbers are 394, 351, 388, 688

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

Apply this formula for all numbers.

Step1:

LCM(394, 351) = 138294

GCD(394, 351) = ( 394 x 351 ) / 138294

= 394 / 351

= 394

Step2:

LCM(1, 388) = 388

GCD(1, 388) = ( 1 x 388 ) / 388

= 1 / 388

= 1

Step3:

LCM(1, 688) = 688

GCD(1, 688) = ( 1 x 688 ) / 688

= 1 / 688

= 1

So, Greatest Common Divisor of 394, 351, 388, 688 is 1
