Answer:
The least common multiple = 2 × 3² × 5²
Explanation:
* The common multiple of some numbers must be greater than
the numbers or equal the greatest one and it must divisible by
the all numbers (can divided by them without remainder
- Ex: 12 is the common multiple of 3 , 4 and 6
- It is greater than them and it is divisible by 3 , 4 and 6
* How to find the common multiple
- Factorize each number using prime factors 92 , 3 , 5 , 7 , 11 , .....)
- Take all the common factors and multiply them by each other
* Lets solve our problem
∵ 15 = 3 × 5
∵ 18 = 3 × 3 × 2 = 3² × 2
∵ 25 = 5 × 5 = 5²
∴ The least common multiple = 2 × 3² × 5² = 450
* The least common multiple is 450
