Given numbers are 207, 222, 990, 243

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

Apply this formula for all numbers.

Step1:

LCM(207, 222) = 15318

GCD(207, 222) = ( 207 x 222 ) / 15318

= 207 / 222

= 207

Step2:

LCM(3, 990) = 990

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

= 3 / 990

= 3

Step3:

LCM(3, 243) = 243

GCD(3, 243) = ( 3 x 243 ) / 243

= 3 / 243

= 3

So, Greatest Common Divisor of 207, 222, 990, 243 is 3
