Given numbers are 990, 834, 642, 423

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

Apply this formula for all numbers.

Step1:

LCM(990, 834) = 137610

GCD(990, 834) = ( 990 x 834 ) / 137610

= 990 / 834

= 990

Step2:

LCM(6, 642) = 642

GCD(6, 642) = ( 6 x 642 ) / 642

= 6 / 642

= 6

Step3:

LCM(6, 423) = 846

GCD(6, 423) = ( 6 x 423 ) / 846

= 6 / 423

= 6

So, Greatest Common Divisor of 990, 834, 642, 423 is 3
