2. Steps to find factors of 828 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 828 using the division method, follow these steps:

  • Step 1. Start dividing 828 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 828, which is 2. Divide 828 by 2 to obtain the quotient (414).
    828 ÷ 2 = 414
  • Step 3. Repeat step 1 with the obtained quotient (414).
    414 ÷ 2 = 207
    207 ÷ 3 = 69
    69 ÷ 3 = 23
    23 ÷ 23 = 1

So, the prime factorization of 828 is, 828 = 2 x 2 x 3 x 3 x 23.

Method 2: Factor Tree Method

We can follow the same procedure using the factor tree of 828 as shown below:

So, the prime factorization of 828 is, 828 = 2 x 2 x 3 x 3 x 23.

3. Find factors of 828 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 828 would be the two numbers which, when multiplied, give 828 as the result.

The following table represents the calculation of factors of 828 in pairs:

Factor Pair Pair Factorization
1 and 828 1 x 828 = 828
2 and 414 2 x 414 = 828
3 and 276 3 x 276 = 828
4 and 207 4 x 207 = 828
6 and 138 6 x 138 = 828
9 and 92 9 x 92 = 828
12 and 69 12 x 69 = 828
18 and 46 18 x 46 = 828
23 and 36 23 x 36 = 828

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 828. They are called negative pair factors.

Hence, the negative pairs of 828 would be ( -1 , -828 ) , ( -2 , -414 ) , ( -3 , -276 ) , ( -4 , -207 ) , ( -6 , -138 ) , ( -9 , -92 ) , ( -12 , -69 ) , ( -18 , -46 ) and ( -23 , -36 ) .

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

  • Each number is a factor of itself. Eg. 828 is a factor of itself.
  • 1 is a factor of every number. Eg. 1 is a factor of 828.
  • Every number is a factor of zero (0), since 828 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, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828 are exact divisors of 828.
  • Factors of 828 are 1, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828. Each factor divides 828 without leaving a remainder.
  • Every factor of a number is less than or equal to the number, eg. 1, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828 are all less than or equal to 828.
