# Factors of 84—with Easy division and prime factorization

Contents

**Factors Of 84**

**The factors of 84 are the numbers that evenly divide the original number.**

As an example, 2 is the factor of 84, since 84 divided by 2 equals 42. Pair factors are numbers that, when multiplied together, give the original number. As an example, 2 and 42 are pair factors.

Let’s learn how to find the factors and pair factors along with prime factors.

**What are the Factors of -84?**

When we multiply two numbers, and we get -84 as a product, those numbers are the factors of -84.

**Here is the explanation:**

-1 × 84 = -84

1 × -84 = -84

-2 × 42 = -84

2 × -42 = -84

-3 × 28 = -84

3 × 28 = -84

-4 × 21 = -84

4 × -21 = -84

-6 × 14 = -84

6 × -14 = -84

-7 × 12 = -84

7 × -12 = -84

We can get -84 by having (-1, 84), (-2, 42), (-3, 28), (-4, 21), (-6, 14), and (-7, 12) as a pair of factors. Similarly, we can also get -84 by having (1, -84), (2, -42), (3, -28), (4, -21), (6, -14), and (7, -12) as a pair of factors.

**Pair Factors of 84**

In order to find the factor pairs, multiply two numbers in a pair to get the original number as 84, such as:

1 × 84 = 84

2 × 42 = 84

3 × 28 = 84

4 × 21 = 84

6 × 14 = 84

7 × 12 = 84

Thus, the factor pairs are (1, 84), (2, 42), (3, 28), (4, 21), (6, 14), and (7, 12). So, we can evaluate the unique factors of number 84 as follows:

Factors of 84 : 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42 and 84

As a pair factor of 84, we can also write a negative number since after multiplying two negative factors, we will get a positive number.

(-1) × (-84) = 84

(-2) × (-42) = 84

(-3) × (-28) = 84

(-4) × (-21) = 84

(-6) × (-14) = 84

(-7) × (-12) = 84

As a result, the negative pair factors are (-1, -84), (-2, -42), (-3, -28), (-4, -21), (-6, -14), and (-7, -12).

**How to Calculate the Factors of 84?**

To find the factors, we need to divide the original number by all the natural numbers until we get a quotient equal to 1.

84 ÷ 1 = 84

84 ÷ 2 = 42

84 ÷ 3 = 28

84 ÷ 4 = 21

84 ÷ 6 = 14

84 ÷ 7 = 12

84 ÷ 12 = 7

84 ÷ 14 = 6

84 ÷ 21 = 4

84 ÷ 28 = 3

84 ÷ 42 = 2

84 ÷ 84 = 1

Thus, the required factors are: 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42 and 84.

**Prime Factorization of 84**

Since 84 is a composite number, we can find its prime factors using the steps below.

- To begin, divide 84 with the smallest prime factor, i.e., 2.

84 ÷ 2 = 42

Divide 42 by 2 once more.

42 ÷ 2 = 21

We get a fraction if we divide 21 by 2, so it cannot be a factor.

- Next, we will look at prime numbers 3, 5, 7, and so on.

21 ÷ 3 = 7

7 ÷ 3 = 2.33,not a factor.

Move to the next prime number, 5.

Again, dividing 7 by 5 gives a fraction value.

7 ÷ 5 = 1.4, not a factor.

We move on to prime number 7.

- When we divide 7 by 7, we get:

7 ÷ 7 = 1

- As a result, we are unable to proceed with the division. So, 84 is a prime factorization of
**2 × 2 × 3 × 7 or 22 × 3 × 7**, where 2, 3, and 7 are prime numbers.

**Solved Examples**

**Q.1: If Ali has 84 candies and has to distribute those to 7 members of the house, including her, how many candies each member gets?**

**Solution**:

Number of candies, Ali has = 84

Members in the house including Ali = 7

Therefore, each member will get = 84/7 = 12candies.

**Q.2: What are the factors of 84 and 114?**

Answer:

Factors of 84 = **1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 84.**

Factors of 114 =** 1, 2, 3, 6, 19, 38, 57, 114.**

The common factors of 84 and 114 are 1,2,3, and 6.
