### Example: Find factors of 287

• Divide 287 by 1: 287 ÷ 1 : Remainder = 0
• Divide 287 by 7: 287 ÷ 7 : Remainder = 0
• Divide 287 by 41: 287 ÷ 41 : Remainder = 0
• Divide 287 by 287: 287 ÷ 287 : Remainder = 0

Hence, Factors of 287 are 1, 7, 41, and 287

#### 2. Steps to find factors of 287 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 287 using the division method, follow these steps:

• Step 1. Start dividing 287 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 287, which is 7. Divide 287 by 7 to obtain the quotient (41).
287 ÷ 7 = 41
• Step 3. Repeat step 1 with the obtained quotient (41).
41 ÷ 41 = 1

So, the prime factorization of 287 is, 287 = 7 x 41.

#### Method 2: Factor Tree Method

We can follow the same procedure using the factor tree of 287 as shown below:

So, the prime factorization of 287 is, 287 = 7 x 41.

#### 3. Find factors of 287 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 287 would be the two numbers which, when multiplied, give 287 as the result.

The following table represents the calculation of factors of 287 in pairs:

Factor Pair Pair Factorization
1 and 287 1 x 287 = 287
7 and 41 7 x 41 = 287

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 287. They are called negative pair factors.

Hence, the negative pairs of 287 would be ( -1 , -287 ) , ( -7 , -41 ) .

#### How do you explain factors?

In mathematics, a factor is a number or also it can be an algebraic expression that divides another number or any expression completely and that too without leaving any remainder. A factor of a number can be positive or negative.

#### Properties of factors

• Every number is a factor of zero (0), since 287 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, 41, 287 are exact divisors of 287.
• Factors of 287 are 1, 7, 41, 287. Each factor divides 287 without leaving a remainder.
