Factors of 2

Factors of 2 are the numbers which get multiplied and produce the result as 2. Suppose, when we multiply 2 and 3, we get 6, i.e. 2 × 3 = 6 such that 2 and 3 are the factors of 6. We know that 2 is the smallest prime number and the smallest positive even number. Hence, finding the factors of 2 will be easy and interesting. In this article, you will understand how to find the factors of a number 2 and prime factors of 2.

What are the Factors of 2?

As we know, 2 is a prime number, it has only two factors, i.e. 1 and 2. Also, we know that the factors of 2 are the exact divisors of that number. There is another way to represent the factors of any number, i.e. by arranging the number of objects (equal to the number for which we need to find the factors).

In this case, we will be arranging two dots in different patterns such as:

. . and :

The first pattern shows two dots are arranged in one row and 2 columns, i.e. 1 × 2.

The second pattern shows two dots arranged in two rows and 1 column, i.e. 2 × 1.

Factor pairs of 2

From the above patterns, we can write the factor pairs as:

1 × 2 = 2; (1, 2)

2 × 1 = 2; (2, 1)

These are the positive pair factors for 2.

Therefore, the factors of 2 are: 1 and 2.

We can also write the negative pair factors of 2 such as:

(-1) × (-2) = 2

(-2) × (-1) = 2

Thus, the negative pair factors of 2 are (-1, -2) and (-2, -1).

How to calculate Prime Factors of 2?

We know that 2 is the smallest prime number. We cannot factor it further since the factor of any number will be less than or equal to that number.

Therefore, there are no other prime factors other than 2 itself.
