Given numbers are 834, 909, 990, 621

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

Apply this formula for all numbers.

Step1:

LCM(834, 909) = 252702

GCD(834, 909) = ( 834 x 909 ) / 252702

= 834 / 909

= 834

Step2:

LCM(3, 990) = 990

GCD(3, 990) = ( 3 x 990 ) / 990

= 3 / 990

= 3

Step3:

LCM(3, 621) = 621

GCD(3, 621) = ( 3 x 621 ) / 621

= 3 / 621

= 3

So, Greatest Common Divisor of 834, 909, 990, 621 is 3
