Steps to find factors of 800 in pair

Example: Find factors of 800 in pair

Factor Pair Pair Factorization
1 and 800 1 x 800 = 800
2 and 400 2 x 400 = 800
4 and 200 4 x 200 = 800
5 and 160 5 x 160 = 800
8 and 100 8 x 100 = 800
10 and 80 10 x 80 = 800
16 and 50 16 x 50 = 800
20 and 40 20 x 40 = 800
25 and 32 25 x 32 = 800

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 800. They are called negative pair factors.

Hence, the negative pairs of 800 would be ( -1 , -800 ) .

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 800 are 1 , 2 , 4 , 5 , 8 , 10 , 16 , 20 , 25 , 32 , 40 , 50 , 80 , 100 , 160 , 200 , 400 , 800. So, factors of 800 in pair are (1,800), (2,400), (4,200), (5,160), (8,100), (10,80), (16,50), (20,40), (25,32).

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. 800 is a factor of itself.
  • 1 is a factor of every number. Eg. 1 is a factor of 800.
  • Every number is a factor of zero (0), since 800 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, 16, 20, 25, 32, 40, 50, 80, 100, 160, 200, 400, 800 are exact divisors of 800.
  • Factors of 800 are 1, 2, 4, 5, 8, 10, 16, 20, 25, 32, 40, 50, 80, 100, 160, 200, 400, 800. Each factor divides 800 without leaving a remainder.
  • Every factor of a number is less than or equal to the number, eg. 1, 2, 4, 5, 8, 10, 16, 20, 25, 32, 40, 50, 80, 100, 160, 200, 400, 800 are all less than or equal to 800.

Steps to find Factors of 800

  • Step 1. Find all the numbers that would divide 800 without leaving any remainder. Starting with the number 1 upto 400 (half of 800). The number 1 and the number itself are always factors of the given number.
    800 ÷ 1 : Remainder = 0
    800 ÷ 2 : Remainder = 0
    800 ÷ 4 : Remainder = 0
    800 ÷ 5 : Remainder = 0
    800 ÷ 8 : Remainder = 0
    800 ÷ 10 : Remainder = 0
    800 ÷ 16 : Remainder = 0
    800 ÷ 20 : Remainder = 0
    800 ÷ 25 : Remainder = 0
    800 ÷ 32 : Remainder = 0
    800 ÷ 40 : Remainder = 0
    800 ÷ 50 : Remainder = 0
    800 ÷ 80 : Remainder = 0
    800 ÷ 100 : Remainder = 0
    800 ÷ 160 : Remainder = 0
    800 ÷ 200 : Remainder = 0
    800 ÷ 400 : Remainder = 0
    800 ÷ 800 : Remainder = 0

Hence, Factors of 800 are 1, 2, 4, 5, 8, 10, 16, 20, 25, 32, 40, 50, 80, 100, 160, 200, 400, and 800
