The greatest common divisor of the two numbers is 15 while their least common multiple is 90. If one of the numbers is 30, then the other number is?
The greatest common divisor of the two numbers is 15 while their least common multiple is 90. If one of the numbers is 30, then the other number is?
Explanation
45 is the correct answer
LCM(a,b) × HCF(a,b) = a × b LCM * HCF = One Number * Other Number 15 * 90 = 30 * Other number Hence, Other number = (90 * 15)/30 = 45
