1. Steps to find factors of 481 using Division Method

Example: Find factors of 481

  • Divide 481 by 1: 481 ÷ 1 : Remainder = 0
  • Divide 481 by 13: 481 ÷ 13 : Remainder = 0
  • Divide 481 by 37: 481 ÷ 37 : Remainder = 0
  • Divide 481 by 481: 481 ÷ 481 : Remainder = 0

Hence, Factors of 481 are 1, 13, 37, and 481

2. Steps to find factors of 481 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 481 using the division method, follow these steps:

  • Step 1. Start dividing 481 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 481, which is 13. Divide 481 by 13 to obtain the quotient (37).
    481 ÷ 13 = 37
  • Step 3. Repeat step 1 with the obtained quotient (37).
    37 ÷ 37 = 1

So, the prime factorization of 481 is, 481 = 13 x 37.

Method 2: Factor Tree Method

We can follow the same procedure using the factor tree of 481 as shown below:

So, the prime factorization of 481 is, 481 = 13 x 37.

3. Find factors of 481 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 481 would be the two numbers which, when multiplied, give 481 as the result.

The following table represents the calculation of factors of 481 in pairs:

Factor Pair Pair Factorization
1 and 481 1 x 481 = 481
13 and 37 13 x 37 = 481

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 481. They are called negative pair factors.

Hence, the negative pairs of 481 would be ( -1 , -481 ) , ( -13 , -37 ) .

How can we define factors?

In mathematics a factor is a number which divides into another without leaving any remainder. Or we can say, any two numbers that multiply to give a product are both factors of that product. It can be both positive or negative.

Properties of factors

  • Every factor of a number is an exact divisor of that number, example 1, 13, 37, 481 are exact divisors of 481.
  • Every number other than 1 has at least two factors, namely the number itself and 1.
  • Each number is a factor of itself. Eg. 481 is a factor of itself.
  • 1 is a factor of every number. Eg. 1 is a factor of 481.
