2. Steps to find factors of 2002 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 2002 using the division method, follow these steps:

  • Step 1. Start dividing 2002 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 2002, which is 2. Divide 2002 by 2 to obtain the quotient (1001).
    2002 ÷ 2 = 1001
  • Step 3. Repeat step 1 with the obtained quotient (1001).
    1001 ÷ 7 = 143
    143 ÷ 11 = 13
    13 ÷ 13 = 1

So, the prime factorization of 2002 is, 2002 = 2 x 7 x 11 x 13.

Method 2: Factor Tree Method

We can follow the same procedure using the factor tree of 2002 as shown below:

So, the prime factorization of 2002 is, 2002 = 2 x 7 x 11 x 13.

3. Find factors of 2002 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 2002 would be the two numbers which, when multiplied, give 2002 as the result.

The following table represents the calculation of factors of 2002 in pairs:

Factor Pair Pair Factorization
1 and 2002 1 x 2002 = 2002
2 and 1001 2 x 1001 = 2002
7 and 286 7 x 286 = 2002
11 and 182 11 x 182 = 2002
13 and 154 13 x 154 = 2002
14 and 143 14 x 143 = 2002
22 and 91 22 x 91 = 2002
26 and 77 26 x 77 = 2002

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 2002. They are called negative pair factors.

Hence, the negative pairs of 2002 would be ( -1 , -2002 ) , ( -2 , -1001 ) , ( -7 , -286 ) , ( -11 , -182 ) , ( -13 , -154 ) , ( -14 , -143 ) , ( -22 , -91 ) and ( -26 , -77 ) .

How do you explain factors?

In mathematics, a factor is a number or also it can be an algebraic expression that divides another number or any expression completely and that too without leaving any remainder. A factor of a number can be positive or negative.

Properties of factors

  • Each number is a factor of itself. Eg. 2002 is a factor of itself.
  • 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, 7, 11, 13, 14, 22, 26, 77, 91, 143, 154, 182, 286, 1001, 2002 are exact divisors of 2002.
  • 1 is a factor of every number. Eg. 1 is a factor of 2002.
  • Every number is a factor of zero (0), since 2002 x 0 = 0.
