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

Apply this formula for all numbers.

Step1:

LCM(578, 816) = 13872

GCD(578, 816) = ( 578 x 816 ) / 13872

= 578 / 816

= 578

Step2:

LCM(34, 938) = 15946

GCD(34, 938) = ( 34 x 938 ) / 15946

= 34 / 938

= 34

Step3:

LCM(2, 688) = 688

GCD(2, 688) = ( 2 x 688 ) / 688

= 2 / 688

= 2

So, Greatest Common Divisor of 578, 816, 938, 688 is 2
