2. Steps to find factors of 1140 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 1140 using the division method, follow these steps:

  • Step 1. Start dividing 1140 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 1140, which is 2. Divide 1140 by 2 to obtain the quotient (570).
    1140 ÷ 2 = 570
  • Step 3. Repeat step 1 with the obtained quotient (570).
    570 ÷ 2 = 285
    285 ÷ 3 = 95
    95 ÷ 5 = 19
    19 ÷ 19 = 1

So, the prime factorization of 1140 is, 1140 = 2 x 2 x 3 x 5 x 19.

Method 2: Factor Tree Method

We can follow the same procedure using the factor tree of 1140 as shown below:

So, the prime factorization of 1140 is, 1140 = 2 x 2 x 3 x 5 x 19.

3. Find factors of 1140 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 1140 would be the two numbers which, when multiplied, give 1140 as the result.

The following table represents the calculation of factors of 1140 in pairs:

Factor Pair Pair Factorization
1 and 1140 1 x 1140 = 1140
2 and 570 2 x 570 = 1140
3 and 380 3 x 380 = 1140
4 and 285 4 x 285 = 1140
5 and 228 5 x 228 = 1140
6 and 190 6 x 190 = 1140
10 and 114 10 x 114 = 1140
12 and 95 12 x 95 = 1140
15 and 76 15 x 76 = 1140
19 and 60 19 x 60 = 1140
20 and 57 20 x 57 = 1140
30 and 38 30 x 38 = 1140

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 1140. They are called negative pair factors.

Hence, the negative pairs of 1140 would be ( -1 , -1140 ) , ( -2 , -570 ) , ( -3 , -380 ) , ( -4 , -285 ) , ( -5 , -228 ) , ( -6 , -190 ) , ( -10 , -114 ) , ( -12 , -95 ) , ( -15 , -76 ) , ( -19 , -60 ) , ( -20 , -57 ) and ( -30 , -38 ) .

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. 1140 is a factor of itself.
  • 1 is a factor of every number. Eg. 1 is a factor of 1140.
  • Every number is a factor of zero (0), since 1140 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, 5, 6, 10, 12, 15, 19, 20, 30, 38, 57, 60, 76, 95, 114, 190, 228, 285, 380, 570, 1140 are exact divisors of 1140.
