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

Apply this formula for all numbers.

Step1:

LCM(638, 800) = 255200

GCD(638, 800) = ( 638 x 800 ) / 255200

= 638 / 800

= 638

Step2:

LCM(2, 392) = 392

GCD(2, 392) = ( 2 x 392 ) / 392

= 2 / 392

= 2

So, Greatest Common Divisor of 638, 800, 392 is 2
