To determine if 220 and 375 are prime numbers, we need to check if they have any divisors other than 1 and themselves.
1. **220**:
- It is an even number, which means it is divisible by 2.
- Specifically, \( 220 = 2 \times 110 \).
- Since 220 has divisors other than 1 and itself, it is **not a prime number**.
2. **375**:
- To check if 375 is prime, we can try dividing it by some small prime numbers.
- It ends in 5, which means it is divisible by 5. Specifically, \( 375 = 5 \times 75 \).
- Since 375 has divisors other than 1 and itself, it is **not a prime number**.
In conclusion, both 220 and 375 are not prime numbers.
