Steps to find factors of 66 in pair

Example: Find factors of 66 in pair

Factor Pair Pair Factorization
1 and 66 1 x 66 = 66
2 and 33 2 x 33 = 66
3 and 22 3 x 22 = 66
6 and 11 6 x 11 = 66

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 66. They are called negative pair factors.

Hence, the negative pairs of 66 would be ( -1 , -66 ) .

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 66 are 1 , 2 , 3 , 6 , 11 , 22 , 33 , 66. So, factors of 66 in pair are (1,66), (2,33), (3,22), (6,11).

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

  • Each number is a factor of itself. Eg. 66 is a factor of itself.
  • 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, 3, 6, 11, 22, 33, 66 are exact divisors of 66.
  • 1 is a factor of every number. Eg. 1 is a factor of 66.
  • Every number is a factor of zero (0), since 66 x 0 = 0.

Steps to find Factors of 66

  • Step 1. Find all the numbers that would divide 66 without leaving any remainder. Starting with the number 1 upto 33 (half of 66). The number 1 and the number itself are always factors of the given number.
    66 ÷ 1 : Remainder = 0
    66 ÷ 2 : Remainder = 0
    66 ÷ 3 : Remainder = 0
    66 ÷ 6 : Remainder = 0
    66 ÷ 11 : Remainder = 0
    66 ÷ 22 : Remainder = 0
    66 ÷ 33 : Remainder = 0
    66 ÷ 66 : Remainder = 0

Hence, Factors of 66 are 1, 2, 3, 6, 11, 22, 33, and 66

Frequently Asked Questions

  • What is the mean of factors of 66?

    Factors of 66 are 1 , 2 , 3 , 6 , 11 , 22 , 33 , 66. therefore mean of factors of 66 is (1 + 2 + 3 + 6 + 11 + 22 + 33 + 66) / 8 = 18.00.

  • 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.
