2. Steps to find factors of 1040 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 1040 using the division method, follow these steps:

  • Step 1. Start dividing 1040 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 1040, which is 2. Divide 1040 by 2 to obtain the quotient (520).
    1040 ÷ 2 = 520
  • Step 3. Repeat step 1 with the obtained quotient (520).
    520 ÷ 2 = 260
    260 ÷ 2 = 130
    130 ÷ 2 = 65
    65 ÷ 5 = 13
    13 ÷ 13 = 1

So, the prime factorization of 1040 is, 1040 = 2 x 2 x 2 x 2 x 5 x 13.

Method 2: Factor Tree Method

We can follow the same procedure using the factor tree of 1040 as shown below:

So, the prime factorization of 1040 is, 1040 = 2 x 2 x 2 x 2 x 5 x 13.

3. Find factors of 1040 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 1040 would be the two numbers which, when multiplied, give 1040 as the result.

The following table represents the calculation of factors of 1040 in pairs:

Factor Pair Pair Factorization
1 and 1040 1 x 1040 = 1040
2 and 520 2 x 520 = 1040
4 and 260 4 x 260 = 1040
5 and 208 5 x 208 = 1040
8 and 130 8 x 130 = 1040
10 and 104 10 x 104 = 1040
13 and 80 13 x 80 = 1040
16 and 65 16 x 65 = 1040
20 and 52 20 x 52 = 1040
26 and 40 26 x 40 = 1040

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 1040. They are called negative pair factors.

Hence, the negative pairs of 1040 would be ( -1 , -1040 ) , ( -2 , -520 ) , ( -4 , -260 ) , ( -5 , -208 ) , ( -8 , -130 ) , ( -10 , -104 ) , ( -13 , -80 ) , ( -16 , -65 ) , ( -20 , -52 ) and ( -26 , -40 ) .

What are factors?

In mathematics, a factor is that number which divides into another number exactly, without leaving a remainder. A factor of a number can be positive or negative.

Properties of factors

  • Each number is a factor of itself. Eg. 1040 is a factor of itself.
  • 1 is a factor of every number. Eg. 1 is a factor of 1040.
  • Every number is a factor of zero (0), since 1040 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, 4, 5, 8, 10, 13, 16, 20, 26, 40, 52, 65, 80, 104, 130, 208, 260, 520, 1040 are exact divisors of 1040.
