Factors of 2: Sum, Negative Factors, Factor Pairs 

The Factors of 2 are brief as the number 2 is the smallest as well as the First Prime Factor. Furthermore, as a rule, the Factors of Prime numbers will always be the number itself and 1. Factors are numbers that divide a particular number without any remainder. Read on to learn more about the Factors of 2, the Sum of the Factors, the Negative Factors, the Factor Pairs and eight Unique Points of the Factor of 2. 

What are the Factors of 2?

Factors are whole numbers that you can multiply together to get another number. When it comes to 2, there are only two factors which are 1 and 2.

• 1 x 2 = 2
• 2 x 1 = 2

Thus, these are the only two whole numbers that divide evenly into 2 with no remainder.

What are the Negative factors of 2?

As you now know the positive factor of 2. However, you can also consider Negative factors. In the case of 2, multiplying negative integers by each other can result in a positive product.

Therefore, -1 and -2 would also be considered factors of 2:

• 1 x (-2) = -2
• (-2) x (-1) = 2

What are the Factor Pairs of 2?

Additionally, Factor pairs are the two factors listed together. For 2, the Factor pairs are:

• (1, 2)
• (2, 1)

Thus, these pairs represent the two ways you can multiply the factors to get 2.
