Given numbers are 405, 601, 789
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(405, 601) = 243405
GCD(405, 601) = ( 405 x 601 ) / 243405
= 405 / 601
= 405
Step2:
LCM(1, 789) = 789
GCD(1, 789) = ( 1 x 789 ) / 789
= 1 / 789
= 1
So, Greatest Common Divisor of 405, 601, 789 is 1
