Steps to find factors of 2005 in pair

Example: Find factors of 2005 in pair

Factor Pair Pair Factorization
1 and 2005 1 x 2005 = 2005
5 and 401 5 x 401 = 2005

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 2005. They are called negative pair factors.

Hence, the negative pairs of 2005 would be ( -1 , -2005 ) .

Definition of factor pairs?

In mathematics, factor pair are often given as pair of numbers which when multiplied together give the original number. Every natural number is a product of atleast one factor pair. Eg- Factors of 2005 are 1 , 5 , 401 , 2005. So, factors of 2005 in pair are (1,2005), (5,401).

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

  • Every factor of a number is an exact divisor of that number, example 1, 5, 401, 2005 are exact divisors of 2005.
  • Every number other than 1 has at least two factors, namely the number itself and 1.
  • Each number is a factor of itself. Eg. 2005 is a factor of itself.
  • 1 is a factor of every number. Eg. 1 is a factor of 2005.

Steps to find Factors of 2005

  • Step 1. Find all the numbers that would divide 2005 without leaving any remainder. Starting with the number 1 upto 1002 (half of 2005). The number 1 and the number itself are always factors of the given number.
    2005 ÷ 1 : Remainder = 0
    2005 ÷ 5 : Remainder = 0
    2005 ÷ 401 : Remainder = 0
    2005 ÷ 2005 : Remainder = 0

Hence, Factors of 2005 are 1, 5, 401, and 2005

  • What is the mean of factors of 2005?

    Factors of 2005 are 1 , 5 , 401 , 2005. therefore mean of factors of 2005 is (1 + 5 + 401 + 2005) / 4 = 603.00.

  • What do you mean by proper divisors?

    A number x is said to be the proper divisor of y if it divides y completely, given that x is smaller than y.

  • What do you mean by improper divisors?

    An improper divisor of a number is the number itself apart from this any divisor of a given number is a proper divisor.
