Given numbers are 720, 225, 406
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(720, 225) = 3600
GCD(720, 225) = ( 720 x 225 ) / 3600
= 720 / 225
= 720
Step2:
LCM(45, 406) = 18270
GCD(45, 406) = ( 45 x 406 ) / 18270
= 45 / 406
= 45
So, Greatest Common Divisor of 720, 225, 406 is 1
