## How To Find the Factors of 684?

You can find the factors of 684 by using the rules of divisibility. The divisibility rule states that any number, when divided by any other natural number, is said to be divisible by the number if the quotient is the whole number and the resulting remainder is zero.

To find the factors of 684, create a list containing the numbers that are exactly divisible by 684 with zero remainders. One important thing to note is that 1 and 684 are the 684’s factors as every natural number has 1 and the number itself as its factor.

1 is also called the universal factor of every number. The factors of 684 are determined as follows:

$\dfrac{684}{1} = 684$

$\dfrac{684}{2} = 342$

$\dfrac{684}{3} = 228$

$\dfrac{684}{4} = 171$

$\dfrac{684}{6} = 114$

$\dfrac{684}{9} = 76$

$\dfrac{684}{12} = 57$

$\dfrac{684}{18} = 38$

$\dfrac{684}{19} = 36$

$\dfrac{684}{36} = 19$

$\dfrac{684}{38} = 18$

$\dfrac{684}{57} = 12$

$\dfrac{684}{76} = 9$

$\dfrac{684}{114} = 6$

$\dfrac{684}{171} = 4$

$\dfrac{684}{228} = 3$

$\dfrac{684}{342} = 2$

$\dfrac{684}{684} = 1$

Therefore,1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, and 684 are the factors of 684.

### Total Number of Factors of 684

For 684, there are 18 positive factors and 18 negative ones. So in total, there are 36 factors of 684.

To find the total number of factors of the given number, follow the procedure mentioned below:

1. Find the factorization/prime factorization of the given number.
2. Demonstrate the prime factorization of the number in the form of exponent form.
3. Add 1 to each of the exponents of the prime factor.
4. Now, multiply the resulting exponents together. This obtained product is equivalent to the total number of factors of the given number.

By following this procedure, the total number of factors of 684 is given as:

Factorization of 684 is 1 x 2 x 2 x 3 x 3 x 19.

The exponent of 2 and 3 is 2, 1, and 19 is 1.

Adding 1 to each and multiplying them together results in 36.

Therefore, the total number of factors of 684 is 36. 18 are positive, and 18 factors are negative.

### Important Notes

Here are some essential points that must be considered while finding the factors of any given number:

• The factor of any given number must be a whole number.
• The factors of the number cannot be in the form of decimals or fractions.
• Factors can be positive as well as negative.
• Negative factors are the additive inverse of the positive factors of a given number.
• The factor of a number cannot be greater than that number.
• Every even number has 2 as its prime factor, the smallest prime factor.

## Factors of 684 by Prime Factorization

The number 684 is a composite number. Prime factorization is a valuable technique for finding the number’s prime factors and expressing the number as the product of its prime factors.

Before finding the factors of 684 using prime factorization, let us find out what prime factors are. Prime factors are the factors of any given number that are only divisible by 1 and themselves.

To start the prime factorization of 684, start dividing by its most minor prime factor. First, determine that the given number is either even or odd. If it is an even number, then 2 will be the smallest prime factor.

Continue splitting the quotient obtained until 1 is received as the quotient. The prime factorization of 684 can be expressed as:

684 =  2 x 2 x 3 x 3 x 19

## Factors of 684 in Pairs

The factor pairs are the duplet of numbers that, when multiplied together, result in the factorized number. Factor pairs can be more than one depending on the total number of factors given.

For 684, the factor pairs can be found as:

1 x 684 = 684

2 x 342= 684

3 x 228 = 684

4 x 171 = 684

6 x 114  = 684

9 x 76 = 684

12 x 57 = 684

18 x 38 = 684

19 x 36 = 684

The possible factor pairs of 684 are given as (1, 684),(3, 228 ),(4, 171 ),(6, 114 ),(9, 76 ),(12, 57 ),(18, 38 ), and (19, 36 ).

All these numbers in pairs, when multiplied, give 684 as the product.

The negative factor pairs of 684 are given as:

-1 x -684= 684

-3 x -228 = 684

-4 x -171 = 684

-6 x -114  = 684

-9 x -76 = 684

-12 x -57 = 684

-18 x -38 = 684

-19 x -36 = 684

It is important to note that in negative factor pairs, the minus sign has been multiplied by the minus sign, due to which the resulting product is the original positive number. Therefore, -1, -2, -3, -4, -6, -9, -12, -18, -19, -36, -38, -57, -76, -114, -171, -228, -342, and -684 are called negative factors of 684.

The list of all the factors of 684, including positive as well as negative numbers, is given below.

Factor list of 684: 1,-1, 2,-2, 3,-3, 4,-4, 6,-6, 9,-9, 12,-12, 18,-18, 19,-19, 36,-36, 38,-38, 57,-57, 76,-76, 114,-114, 171,-171, 228,-228, 342,-342,  684, and -684
