Math Problem Statement
Find the least number which is exactly divisible by each one of the numbers 12, 16 and 24.
Solution
To find the least number that is exactly divisible by 12, 16, and 24, we need to determine the Least Common Multiple (LCM) of these numbers.
Steps to find the LCM:
-
Prime factorization of each number:
-
Identify the highest powers of all prime factors:
- For : The highest power is (from 16).
- For : The highest power is (from 12 and 24).
-
Multiply these highest powers together to find the LCM:
So, the least number that is exactly divisible by 12, 16, and 24 is 48.
