Given numbers are 840, 406, 498, 744

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

Apply this formula for all numbers.

Step1:

LCM(840, 406) = 24360

GCD(840, 406) = ( 840 x 406 ) / 24360

= 840 / 406

= 840

Step2:

LCM(14, 498) = 3486

GCD(14, 498) = ( 14 x 498 ) / 3486

= 14 / 498

= 14

Step3:

LCM(2, 744) = 744

GCD(2, 744) = ( 2 x 744 ) / 744

= 2 / 744

= 2

So, Greatest Common Divisor of 840, 406, 498, 744 is 2
