What will be the least number which when doubled will be exactly divisible by 12, 18, 21 and 30 ?
Question
Solution 1
To find the least number which when doubled will be exactly divisible by 12, 18, 21 and 30, we need to find the least common multiple (LCM) of these numbers.
Step 1: Prime factorization of each number
- 12 = 2^2 * 3
- 18 = 2 * 3^2
- 21 = 3 * 7
- 30 = 2 * 3 * 5
