GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(393, 249) = 32619
GCD(393, 249) = ( 393 x 249 ) / 32619
= 393 / 249
= 393
Step2:
LCM(3, 405) = 405
GCD(3, 405) = ( 3 x 405 ) / 405
= 3 / 405
= 3
Step3:
LCM(3, 216) = 216
GCD(3, 216) = ( 3 x 216 ) / 216
= 3 / 216
= 3
So, Greatest Common Divisor of 393, 249, 405, 216 is 3
