Given numbers are 342, 996, 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(342, 996) = 56772

GCD(342, 996) = ( 342 x 996 ) / 56772

= 342 / 996

= 342

Step2:

LCM(6, 990) = 990

GCD(6, 990) = ( 6 x 990 ) / 990

= 6 / 990

= 6

Step3:

LCM(6, 621) = 1242

GCD(6, 621) = ( 6 x 621 ) / 1242

= 6 / 621

= 6

So, Greatest Common Divisor of 342, 996, 990, 621 is 3
