Steps to find factors of 11 in pair

Example: Find factors of 11 in pair

Factor Pair Pair Factorization
1 and 11 1 x 11 = 11

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 11. They are called negative pair factors.

Hence, the negative pairs of 11 would be ( -1 , -11 ) , .

Introduction to factor pairs

Factor pair in mathematics is defined as all factors of a given number which when written in pair and multiplied gives the original number. Every natural number is a product of atleast one factor pair. Eg- Factors of 11 are 1 , 11. So, factors of 11 in pair are (1,11).

How can we define factors?

In mathematics a factor is a number which divides into another without leaving any remainder. Or we can say, any two numbers that multiply to give a product are both factors of that product. It can be both positive or negative.

Properties of Factors

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

Steps to find Factors of 11

  • Step 1. Find all the numbers that would divide 11 without leaving any remainder. Starting with the number 1 upto 5 (half of 11). The number 1 and the number itself are always factors of the given number.
    11 ÷ 1 : Remainder = 0
    11 ÷ 11 : Remainder = 0

Hence, Factors of 11 are 1 and 11

Frequently Asked Questions

  • Is 11 a perfect square?

  • 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.
