What are Factors of 2002?
Factors of 2002 are pairs of those numbers whose products result in 2002. These factors are either prime numbers or composite numbers.
How to Find the Factors of 2002?
To find the factors of 2002, we will have to find the list of numbers that would divide 2002 without leaving any remainder.
- 2002/26 = 77; therefore, 26 is a factor of 2002 and 77 is also a factor of 2002.
- 2002/154 = 13; therefore, 154 is a factor of 2002 and 13 is also a factor of 2002.

Factors of 2002 by Prime Factorization
- 2002 ÷ 2 = 1001
Further dividing 1001 by 2 gives a non-zero remainder. So we stop the process and continue dividing the number 1001 by the next smallest prime factor. We stop ultimately if the next prime factor doesn't exist or when we can't divide any further.
So, the prime factorization of 2002 can be written as 21 × 71 × 111 × 131 where 2, 7, 11, 13 are prime.

Example 1: How many factors are there for 2002?
Solution:
The factors of 2002 are too many, therefore if we can find the prime factorization of 2002, then the total number of factors can be calculated using the formula shown below.
If the prime factorization of the number is ax × by × cz where a, b, c are prime, then the total number of factors can be given by (x + 1)(y + 1)(z + 1).
Prime Factorization of 2002 = 21 × 71 × 111 × 131
Therefore, the total number of factors are (1 + 1) × (1 + 1) × (1 + 1) × (1 + 1) = 2 × 2 × 2 × 2 = 16 -
Example 2: Find the LCM and Greatest Common Divisor (GCD) of 2002 and 400.
