The number 11 is a prime number, which means it is only divisible by 1 and itself. As a result, the factors of 11 are limited to those two numbers. In other words, the only positive integers that can divide evenly into 11 are 1 and 11 itself.

To summarize:

Factors of 11: 1, 11

These are the only whole numbers that can divide evenly into 11 without leaving a remainder.

**How many Factors of 11**

The number 11 is a prime number, and as mentioned earlier, it only has two factors: 1 and 11. Therefore, there are exactly two factors of 11.

**Factor Pairs of 11**

Since 11 is a prime number, it only has one pair of factors: (1, 11). This is the only possible factor pair for the number 11.

**All Factors of 11 using Multiplication**

To find all the factors of 11 using multiplication, we can start by multiplying 1 with different numbers and check if the product is equal to 11. Since 11 is a prime number, there will be no other factors apart from 1 and 11.

1 × 11 = 11

Therefore, the factors of 11 using multiplication are:

1, 11

**FAQs on Factor Pairs of 11**

**Q1: What is a factor pair?**A factor pair refers to two numbers that, when multiplied together, result in a given number. In the case of 11, the only factor pair is (1, 11).

**Q2: Why does 11 only have one factor pair?**Since 11 is a prime number, it only has two factors: 1 and 11. A prime number is a number that is divisible only by 1 and itself, which means there are no other factors for 11.

**Q3: Can a number have more than one factor pair?**Yes, numbers that are not prime can have multiple factor pairs. For example, the number 12 has factor pairs (1, 12), (2, 6), and (3, 4). These pairs are obtained by finding two numbers whose product equals 12.

**Q4: How can I determine all the factor pairs of a number?**To determine all the factor pairs of a given number, you can start by finding all the possible divisors of that number. Then, pair up the divisors in such a way that their product equals the given number.
