GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(729, 630) = 51030
GCD(729, 630) = ( 729 x 630 ) / 51030
= 729 / 630
= 729
Step2:
LCM(9, 261) = 261
GCD(9, 261) = ( 9 x 261 ) / 261
= 9 / 261
= 9
Step3:
LCM(9, 399) = 1197
GCD(9, 399) = ( 9 x 399 ) / 1197
= 9 / 399
= 9
So, Greatest Common Divisor of 729, 630, 261, 399 is 3
