Mathematics
ScanSolve AI Answer
To find the Least Common Multiple (LCM) of 5 and 9, we can list the multiples of each number until we find the smallest multiple they have in common.
Multiples of 5: 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, ...
Multiples of 9: 9, 18, 27, 36, 45, 54, ...
The smallest number that appears in both lists is 45.
Alternatively, since 5 and 9 have no common factors other than 1 (they are relatively prime), their LCM is simply their product.
LCM(5, 9) = 5 × 9 = 45
The LCM of 5 and 9 is 45.
