Is 1111 a Composite Number?

To determine whether 1111 is a composite number, we need to check if it has any factors other than 1 and itself.

The number 1111 can be expressed as the product of prime factors. To find the prime factors of 1111, we can use the process of prime factorization.

Let's find the prime factors of 1111:

1. We start by dividing 1111 by the smallest prime number, which is 2. However, 1111 is not divisible by 2. 2. Next, we try dividing 1111 by the next prime number, which is 3. Again, 1111 is not divisible by 3. 3. We continue dividing 1111 by the next prime number, which is 5. Once again, 1111 is not divisible by 5. 4. Finally, we try dividing 1111 by the next prime number, which is 7. Surprisingly, 1111 is divisible by 7.

Therefore, the prime factorization of 1111 is 7 * 7 * 23.

Since 1111 has factors other than 1 and itself, namely 7 and 23, we can conclude that 1111 is a composite number.
