Factors of 320 in pair are (1, 320) , (2, 160) , (4, 80) , (5, 64) , (8, 40) , (10, 32) and (16, 20)

How to find factors of a number in pair

Steps to find factors of 320 in pair

Example: Find factors of 320 in pair

Factor Pair Pair Factorization
1 and 320 1 x 320 = 320
2 and 160 2 x 160 = 320
4 and 80 4 x 80 = 320
5 and 64 5 x 64 = 320
8 and 40 8 x 40 = 320
10 and 32 10 x 32 = 320
16 and 20 16 x 20 = 320

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 320. They are called negative pair factors.

Hence, the negative pairs of 320 would be ( -1 , -320 ) .

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 320 are 1 , 2 , 4 , 5 , 8 , 10 , 16 , 20 , 32 , 40 , 64 , 80 , 160 , 320. So, factors of 320 in pair are (1,320), (2,160), (4,80), (5,64), (8,40), (10,32), (16,20).

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. 320 is a factor of itself.
  • 1 is a factor of every number. Eg. 1 is a factor of 320.
  • Every number is a factor of zero (0), since 320 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, 32, 40, 64, 80, 160, 320 are exact divisors of 320.
  • Factors of 320 are 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320. Each factor divides 320 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, 32, 40, 64, 80, 160, 320 are all less than or equal to 320.

Steps to find Factors of 320

  • Step 1. Find all the numbers that would divide 320 without leaving any remainder. Starting with the number 1 upto 160 (half of 320). The number 1 and the number itself are always factors of the given number.
    320 ÷ 1 : Remainder = 0
    320 ÷ 2 : Remainder = 0
    320 ÷ 4 : Remainder = 0
    320 ÷ 5 : Remainder = 0
    320 ÷ 8 : Remainder = 0
    320 ÷ 10 : Remainder = 0
    320 ÷ 16 : Remainder = 0
    320 ÷ 20 : Remainder = 0
    320 ÷ 32 : Remainder = 0
    320 ÷ 40 : Remainder = 0
    320 ÷ 64 : Remainder = 0
    320 ÷ 80 : Remainder = 0
    320 ÷ 160 : Remainder = 0
    320 ÷ 320 : Remainder = 0

Hence, Factors of 320 are 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, and 320
