Given numbers are 723, 840, 576, 309
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(723, 840) = 202440
GCD(723, 840) = ( 723 x 840 ) / 202440
= 723 / 840
= 723
Step2:
LCM(3, 576) = 576
GCD(3, 576) = ( 3 x 576 ) / 576
= 3 / 576
= 3
Step3:
LCM(3, 309) = 309
GCD(3, 309) = ( 3 x 309 ) / 309
= 3 / 309
= 3
So, Greatest Common Divisor of 723, 840, 576, 309 is 3
