Steps to find factors of 99 in pair

Example: Find factors of 99 in pair

Factor Pair Pair Factorization
1 and 99 1 x 99 = 99
3 and 33 3 x 33 = 99
9 and 11 9 x 11 = 99

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 99. They are called negative pair factors.

Hence, the negative pairs of 99 would be ( -1 , -99 ) .

What does factor pairs of a number mean?

Factor pairs are those factors in pair that can give original number when multiplied. Every natural number is a product of atleast one factor pair. Eg- Factors of 99 are 1 , 3 , 9 , 11 , 33 , 99. So, factors of 99 in pair are (1,99), (3,33), (9,11).

How can we define factors?

In mathematics, a factor is a number which divides into another number exactly, without leaving any remainder. A factor of a number can be positive of negative.

Properties of Factors

  • Every number is a factor of zero (0), since 99 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, 3, 9, 11, 33, 99 are exact divisors of 99.
  • Factors of 99 are 1, 3, 9, 11, 33, 99. Each factor divides 99 without leaving a remainder.

Steps to find Factors of 99

  • Step 1. Find all the numbers that would divide 99 without leaving any remainder. Starting with the number 1 upto 49 (half of 99). The number 1 and the number itself are always factors of the given number.
    99 ÷ 1 : Remainder = 0
    99 ÷ 3 : Remainder = 0
    99 ÷ 9 : Remainder = 0
    99 ÷ 11 : Remainder = 0
    99 ÷ 33 : Remainder = 0
    99 ÷ 99 : Remainder = 0

Hence, Factors of 99 are 1, 3, 9, 11, 33, and 99
