# Factors of 8

## Introduction

Numbers are a fundamental part of our everyday lives, and understanding them helps us solve various problems. One key concept in mathematics is the study of factors. Factors are numbers that divide a given integer without leaving a remainder. In this guide, we'll explore the factors of 8, learn different methods to find these factors, and answer some common questions.

## What are the Factors of 8?

The factors of 8 are the numbers that can divide 8 without leaving a remainder. In simpler terms, the numbers that multiply together to make 8 are its factors. These factors include 1, 2, 4, and 8.

## Positive and Negative Pair Factors of 8

Factors can be both positive and negative. For every positive factor pair, there is a corresponding negative pair.

### Positive Pair Factors of 8

Factor Pair | Product |
---|---|

(1, 8) | 1 x 8 = 8 |

(2, 4) | 2 x 4 = 8 |

### Negative Pair Factors of 8

Factor Pair | Product |
---|---|

(-1, -8) | -1 x -8 = 8 |

(-2, -4) | -2 x -4 = 8 |

## Methods to Find the Factors of 8

### Prime Factorization Method

Prime factorization involves breaking down a number into its prime factors. For 8, the prime factorization is:

8=2×2×2=2^{3}

So, the prime factors of 8 are 2, and the factors are 1, 2, 4, and 8.

### Listing Method

The listing method involves listing all positive integers that divide 8 evenly. We list numbers from 1 to 8 and see which ones divide 8 without a remainder.

Number | Division Result | Factor? |
---|---|---|

1 | 8 ÷ 1 = 8 | Yes |

2 | 8 ÷ 2 = 4 | Yes |

3 | 8 ÷ 3 = 2.67 | No |

4 | 8 ÷ 4 = 2 | Yes |

5 | 8 ÷ 5 = 1.6 | No |

6 | 8 ÷ 6 = 1.33 | No |

7 | 8 ÷ 7 = 1.14 | No |

8 | 8 ÷ 8 = 1 | Yes |

### Division Method

The division method involves dividing 8 by all numbers less than or equal to it. If the result is a whole number, the divisor is a factor of 8.

- 8÷1=88 ÷ 1 = 88÷1=8 (Factors: 1 and 8)
- 8÷2=48 ÷ 2 = 48÷2=4 (Factors: 2 and 4)
