### Example: Find factors of 623

• Divide 623 by 1: 623 ÷ 1 : Remainder = 0
• Divide 623 by 7: 623 ÷ 7 : Remainder = 0
• Divide 623 by 89: 623 ÷ 89 : Remainder = 0
• Divide 623 by 623: 623 ÷ 623 : Remainder = 0

Hence, Factors of 623 are 1, 7, 89, and 623

#### 2. Steps to find factors of 623 using Prime Factorization

A prime number is a number that has exactly two factors, 1 and the number itself. Prime factorization of a number means breaking down of the number into the form of products of its prime factors.

There are two different methods that can be used for the prime factorization.

#### Method 1: Division Method

To find the primefactors of 623 using the division method, follow these steps:

• Step 1. Start dividing 623 by the smallest prime number, i.e., 2, 3, 5, and so on. Find the smallest prime factor of the number.
• Step 2. After finding the smallest prime factor of the number 623, which is 7. Divide 623 by 7 to obtain the quotient (89).
623 ÷ 7 = 89
• Step 3. Repeat step 1 with the obtained quotient (89).
89 ÷ 89 = 1

So, the prime factorization of 623 is, 623 = 7 x 89.

#### Method 2: Factor Tree Method

We can follow the same procedure using the factor tree of 623 as shown below:

So, the prime factorization of 623 is, 623 = 7 x 89.

#### 3. Find factors of 623 in Pairs

Pair factors of a number are any two numbers which, which on multiplying together, give that number as a result. The pair factors of 623 would be the two numbers which, when multiplied, give 623 as the result.

The following table represents the calculation of factors of 623 in pairs:

Factor Pair Pair Factorization
1 and 623 1 x 623 = 623
7 and 89 7 x 89 = 623

Since the product of two negative numbers gives a positive number, the product of the negative values of both the numbers in a pair factor will also give 623. They are called negative pair factors.

Hence, the negative pairs of 623 would be ( -1 , -623 ) , ( -7 , -89 ) .

#### What is the definition of factors?

In mathematics, factors are number, algebraic expressions which when multiplied together produce desired product. A factor of a number can be positive or negative.

#### Properties of factors

• Every number is a factor of zero (0), since 623 x 0 = 0.
• Every number other than 1 has at least two factors, namely the number itself and 1.
• Every factor of a number is an exact divisor of that number, example 1, 7, 89, 623 are exact divisors of 623.
• Factors of 623 are 1, 7, 89, 623. Each factor divides 623 without leaving a remainder.

#### Examples of Factors

Joy wants to calculate mean of all the factors of 623. Help him in finding the mean of 623.

Factors of 623 are 1, 7, 89, 623.
To calculate the mean we need to calculate the sum of factors first. Sum of factors of 623 is 1 + 7 + 89 + 623 = 720.
Hence, the mean of factors of 623 is 720 ÷ 4 = 180.00.
