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

Apply this formula for all numbers.

Step1:

LCM(840, 294) = 5880

GCD(840, 294) = ( 840 x 294 ) / 5880

= 840 / 294

= 840

Step2:

LCM(42, 623) = 3738

GCD(42, 623) = ( 42 x 623 ) / 3738

= 42 / 623

= 42

So, Greatest Common Divisor of 840, 294, 623 is 7
