# Factors of 2 – Easy Factors Pairs and Prime Factors

Contents

The first even prime number is 2 in numbers. In addition to the said fact, if we multiply 2 by itself, it is the only number that gives the same result, which is 4. Here you will learn the factors of 2 in detail.

In this discussion, you will learn that 2 is the multiple of all even numbers. 2 can have positive and negative factors. For a better understanding, let’s calculate the factors of 2, prime factors of 2, and factors of 2 in pairs.

**Factors of 2**

**Factors of 2:** 1 and 2.

**Prime Factorization of 2:** 2

**What Are the Factors of 2?**

Factors of 2 on multiplying give the result 2.

1 and 2 are the only factors of 2.

You can see that

-1 × -2 = 2

As the product of any two negative numbers is a positive number, (-1, -2) are also factors of 2.

**Factors of -2**

When we multiply two numbers to get the product -2, it comes the following:

-1 x 2 = -2

1 x -2 = -2

Therefore, we have two possible pairs of factors of -2 as ( -1 x 2 ) and (1 x -2 ).

1 and 47.

(1, 2, 3, 4, 6, 8, 12, 24). We have 1, 2, 3, 4, 6, 8, 12, and 24.

1 and 31.

**Factors of 200**

(1, 2, 4, 5, 8, 10, 20, 25, 40, 50, 100, 200). We have 1, 2, 4, 5, 8, 10, 20, 25, 40, 50, 100, and 200.

**How to Calculate the Factors of 2?**

Let’s look at how to calculate factors of 2.

- Write down the number that needs to be factored in. Let’s say it’s 2.
- Find the two numbers whose product is 2.
- We have 1 x 2 = 2
- Therefore, 1 and 2 are the factors.

**Factors of 2 by Prime Factorization**

The factor of 2 by prime factorization of 2 is 2.

2 is the only prime number that is an even number. Yes, it is the first even and prime digit. It has only two factors, 1 and 2.

**Factors of 2 in Pairs**

The pair factors of 2 are (1,2).

A pair factor can also be negative because any two negative numbers together can give a positive number.

1 x 2 = 2

-1 x -2 = 2

So, we have two pairs, (1, 2) and ( -1, -2). The first one is positive pair and the second one is negative pair as the factors of 2.

**Tips and Tricks**

- Except for 1, every number has at least two factors, namely 1 and the number itself.
- Even numbers have always at least one factor 2 in common.

**FAQs**

**What is the factor pair of 2?**

It is (1, 2). That is a pair of positive factors, and similarly, (-1, -2) is a negative pair. Both bring 2 by multiplying each other.

**What are the factor pair of 2 and 8?**

A factor pair of 2 consists of (1, 2).

Factor pair 8 consists of (2, 4) and (1,8).

**What are factors 2 and 5?**

factors of 2: 1 and 2.

factors of 5: 1 and 5.
