At the elementary level, factors and multiples are basic concepts that we study together. Factors of a number are defined as the number that gives zero remainders when they divide the specific number. Multiples are the numbers that are multiplied by another number to get the specific number.

In other words, factors of a number, when multiplied by a number, give the original number. Consider we have a number 10, its factors are 2 and 5 as the product of 2 and 5 gives us 10. Other factors of 10 are 10 and 1 as their multiplication also gives us 10. The factors of a number can also be negative as the product of two negative numbers is positive, then -1 and -10 are also factors of 10.

In total there are 8 factors of 10 i.e., 1, -1, 2, -2, 5, -5, 10, and -10 but only positive factors are considered when solving a problem also fractions are not considered as factors of any number. Properties of Factors Factors of a number have certain properties.

- Every number other than 0 and 1 possesses at least two factors.
- The factor of a given number is always less than the number.
- The total number of factors of a given number is always finite.
- To determine factors, division and multiplication are used.

Steps to calculate Factors To determine the factors of a given number we need to:

- Write the given number in the terms of the product of two numbers in different ways.
- All the numbers that are written in these products are the factors of the given number.

Solution:

- Given that the number is 1000.
- Write the number in form of the product of two numbers.
- 1000 = 1 × 1000
- 1000 = 2 × 500
- 1000 = 4 × 250
- 1000 = 5 × 200
- 1000 = 8 × 125
- 1000 = 10 × 100
- 1000 = 20 × 50
- 1000 = 25 × 40

All the numbers in the product are factors. Hence, the factors of 1000 are 1, 2, 4, 5, 8, 10, 20, 25, 40, 50, 100, 125, 200, 250, 500 and 1000. Thus, the total number of factors is 16.

### What is the factor of negative 3?

How to Factor Negative Numbers Updated October 26, 2020 By Amy Harris Factors are numbers that – when multiplied together – result in another number, which is known as a product. The laws of multiplication state that when a negative number is multiplied by a positive number, the product will be negative.

- So, if considering a factor pair of a negative product, one of these factors must be negative and the other factor must be positive.
- Otherwise, factoring negative numbers works in the same way as factoring positive numbers.
- The factors of a number entail all of the numbers that can be multiplied by one another to produce that number.

For example, the factors of −8 are: 1 and −8, −1 and 8, 2 and −4, and −2 and 4. This is because each of these factor pairs, when multiplied together, produce −8, as follows: \begin 1 × -8 &= -8 \\ -1 × 8 &= -8 \\ 2 × -4 &= -8 \\ -2 × 4 &= -8 \end Essentially, to factor a negative number, find all of its positive factors, then duplicate them and write a negative sign in front of the duplicates.
