2. Steps to find factors of 1323 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 1323 using the division method, follow these steps:

  • Step 1. Start dividing 1323 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 1323, which is 3. Divide 1323 by 3 to obtain the quotient (441).
    1323 ÷ 3 = 441
  • Step 3. Repeat step 1 with the obtained quotient (441).
    441 ÷ 3 = 147
    147 ÷ 3 = 49
    49 ÷ 7 = 7
    7 ÷ 7 = 1

So, the prime factorization of 1323 is, 1323 = 3 x 3 x 3 x 7 x 7.

Method 2: Factor Tree Method

We can follow the same procedure using the factor tree of 1323 as shown below:

So, the prime factorization of 1323 is, 1323 = 3 x 3 x 3 x 7 x 7.

3. Find factors of 1323 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 1323 would be the two numbers which, when multiplied, give 1323 as the result.

The following table represents the calculation of factors of 1323 in pairs:

Factor Pair Pair Factorization
1 and 1323 1 x 1323 = 1323
3 and 441 3 x 441 = 1323
7 and 189 7 x 189 = 1323
9 and 147 9 x 147 = 1323
21 and 63 21 x 63 = 1323
27 and 49 27 x 49 = 1323

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 1323. They are called negative pair factors.

Hence, the negative pairs of 1323 would be ( -1 , -1323 ) , ( -3 , -441 ) , ( -7 , -189 ) , ( -9 , -147 ) , ( -21 , -63 ) and ( -27 , -49 ) .

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 1323 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, 3, 7, 9, 21, 27, 49, 63, 147, 189, 441, 1323 are exact divisors of 1323.
  • Factors of 1323 are 1, 3, 7, 9, 21, 27, 49, 63, 147, 189, 441, 1323. Each factor divides 1323 without leaving a remainder.
