What will be the least number which when doubled becomes exactly divisible by 9, 15, 21, and 30?
Question
Solution 1
To find the least number which when doubled will be exactly divisible by 9, 15, 21, and 30, we need to find the least common multiple (LCM) of these numbers.
Step 1: Prime factorization of the numbers
- 9 = 3^2
- 15 = 3 * 5
- 21 = 3 * 7
- 30 = 2 * 3 * 5
