1. Steps to find factors of 803 using Division Method

Example: Find factors of 803

  • Divide 803 by 1: 803 ÷ 1 : Remainder = 0
  • Divide 803 by 11: 803 ÷ 11 : Remainder = 0
  • Divide 803 by 73: 803 ÷ 73 : Remainder = 0
  • Divide 803 by 803: 803 ÷ 803 : Remainder = 0

Hence, Factors of 803 are 1, 11, 73, and 803

2. Steps to find factors of 803 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 803 using the division method, follow these steps:

  • Step 1. Start dividing 803 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 803, which is 11. Divide 803 by 11 to obtain the quotient (73).
    803 ÷ 11 = 73
  • Step 3. Repeat step 1 with the obtained quotient (73).
    73 ÷ 73 = 1

So, the prime factorization of 803 is, 803 = 11 x 73.

Method 2: Factor Tree Method

We can follow the same procedure using the factor tree of 803 as shown below:

So, the prime factorization of 803 is, 803 = 11 x 73.

3. Find factors of 803 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 803 would be the two numbers which, when multiplied, give 803 as the result.

The following table represents the calculation of factors of 803 in pairs:

Factor Pair Pair Factorization
1 and 803 1 x 803 = 803
11 and 73 11 x 73 = 803

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 803. They are called negative pair factors.

Hence, the negative pairs of 803 would be ( -1 , -803 ) , ( -11 , -73 ) .

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 803 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, 11, 73, 803 are exact divisors of 803.
  • Factors of 803 are 1, 11, 73, 803. Each factor divides 803 without leaving a remainder.
