Given numbers are 999, 210, 168, 720
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(999, 210) = 69930
GCD(999, 210) = ( 999 x 210 ) / 69930
= 999 / 210
= 999
Step2:
LCM(3, 168) = 168
GCD(3, 168) = ( 3 x 168 ) / 168
= 3 / 168
= 3
Step3:
LCM(3, 720) = 720
GCD(3, 720) = ( 3 x 720 ) / 720
= 3 / 720
= 3
So, Greatest Common Divisor of 999, 210, 168, 720 is 3
