What does it mean if a number "x" is a factor of another number "y"? It means that there is no remainder
when you divide y by x. For a more in-depth understanding of this, we recommend reading our page on factors.
Note that every integer (greater than 1) has at least two factors: 1 and itself. If those are only two
factors that a number has, we call that a prime number. Prime
numbers and prime factorization (more here) are important in
many parts of math.

There are tricks to calculating and finding factors of numbers yourself, as you can see on our factors
page.

**Fun fact**: every integer has one and only one

prime
factorization. That is, one way of expressing the number as a product of primes. This fact is
the fundamental theorem of arithmetic. Every number greater than 1 is either prime, or can be formed
by multiplying primes together.

### What is factorization?

Factorization is a way of expressing a number as a product of other numbers (factors). Factors of a
number are sort of like building blocks of a bigger number. For example, the number 10 has the following
factors: 1, 2, 5, 10. Note that we can also express 10 as 2 x 5.

### How can you determine the factors of 118?

Follow this straightforward method to identify the factors of 118:

- Begin with 1 and the number itself (118), since they're always factors.
- Examine integers from 2 to the square root of 118. If any of them divide 118 without leaving a remainder, they're factors. Additionally, divide 118 by each of these factors to discover their corresponding factors.

Using this technique, we determined the factors of 118 to be 1, 2, 59, 118.

### Real-life uses of factors

Factors are essential in various aspects of daily life. Check out these examples:

**Event planning:** While planning seating for guests, factors assist in identifying the best layout of tables and chairs to seat everyone comfortably. Learn more about factors on our factors page.
**Money management:** Grasping factors can be advantageous when allocating expenses or profits among several people.
**Organization:** Factors contribute to organizing items effectively, such as figuring out the most efficient way to pack boxes or arrange objects on shelves.
