The **least common multiple (LCM)** of 10 and 12 is **60**.

### How to Find the LCM of 10 and 12:

1. **List the multiples of each number:**
   - **Multiples of 10:** 10, 20, 30, 40, 50, **60**, 70, ...
   - **Multiples of 12:** 12, 24, 36, 48, **60**, 72, ...

2. **Identify the smallest common multiple:**
   - The smallest number that appears in both lists is **60**.

### Alternatively, Using Prime Factorization:

1. **Prime factors of 10:**  
   $$10 = 2 	imes 5$$

2. **Prime factors of 12:**  
   $$12 = 2^2 	imes 3$$

3. **Take the highest power of all prime factors:**  
   - $$2^2$$ (from 12)
   - $$3$$ (from 12)
   - $$5$$ (from 10)

4. **Multiply them together:**  
   $$2^2 	imes 3 	imes 5 = 4 	imes 3 	imes 5 = 60$$

So, the LCM of 10 and 12 is **60**.
The least common multiple (LCM) of 10 and 12 is 60.
