Skill: Identify factors of a number

Factors are positive whole numbers that divide a number evenly, with no remainder. Factors always come in pairs that multiply to make the given number.

Example: Find all the factors of $24$.

Start with $1$:

• $1 \times 24 = 24$, so $1$ and $24$ are factors.

Try the next numbers:

• $2 \times 12 = 24$, so $2$ and $12$ are factors.
• $3 \times 8 = 24$, so $3$ and $8$ are factors.
• $4 \times 6 = 24$, so $4$ and $6$ are factors.
• $5$ does not divide $24$ evenly, so it is not a factor.

The factor pairs are:

$$1 \times 24,\quad 2 \times 12,\quad 3 \times 8,\quad 4 \times 6$$

So, the factors of $24$ are:

$$\boxed{1, 2, 3, 4, 6, 8, 12, 24}$$

Remember: factors divide evenly into a number. Multiples are the numbers you get when you multiply a number by $1, 2, 3,\ldots$
