1, 2, 3, 4, 6, 11, 12, 22, 33, 44, 66 and 132

(1, 132), (2, 66), (3, 44),

(4, 33), (6, 22), and (11, 12)



  132 = 2 × 2 × 3 × 11

For Example: 

Dividing 132 by 2 yields a quotient of 66 and a remainder of 0, which means that 2 is a factor of 132. Also, the quotient 66 is a factor of 132.

Prime Factorization of 132

132 is a composite number, that is, it has more than two factors. Prime factorization is the process of expressing the composite number as the product of its prime factors.

 

To carry out the prime factorization of 132, we will keep dividing 132 by its prime factors, until we get the result as 1.

 

As 132 is even, let’s start dividing by 2.

 

132 ÷ 2 = 66

 

66 ÷ 2 = 33

 

Now, divide 33 by 3,

 

33 ÷ 3 = 11

 

11 is a prime number itself, so we will divide 11 by 11;

 

11 ÷ 11 = 1

 

So, the prime factorization of 132 = 2 × 2 × 3 × 11 or \(2^2\) × 3 × 11.

 

Hence the factor tree of 132 can be written as:

Factor Pairs of 132

Factor pairs of 132 are different sets that contain two factors of 132. When these pairs are multiplied together, the product is 132.

 

For example, (3, 44) is a factor pair of 132, as 3 \(\times\) 44 = 132 and both 3 and 44 are factors of 132.

Solved Examples

Example 1: Find the factors common between 88 and 132.

 

Solution:

Factors of 88 = 1, 2, 4, 8, 11, 22, 44 and 88

 

Factors of 132 = 1, 2, 3, 4, 6, 11, 12, 22, 33, 44, 66 and 132

 

Therefore, the factors common between 88 and 132 are 1, 2, 4, 11, 22 and 44.

 

Example 2: Is 9 a factor of 132?

 

Solution:

\(\frac{132}{9}\) = 14 R6

 

So, 9 is not a factor of 132. As the number 9 does not divide 132 exactly. It leaves a remainder of 6. Additionally, the sum of the digits of 132, which is 6, is not divisible by 9.

 

Example 3: A train from Unicorn Village has to travel 132 miles to reach Fairy Land. In one hour the train covers 33 miles. When the train completes travelling for an hour, two trains start from Fairy Land to Unicorn Village. How many trains start from Fairy Land to Unicorn Village during this time?

 

Solution:

Total distance to be covered = 132 miles

 

Distance covered in one hour = 33 miles

 

Time taken to travel 132 miles  = \(\frac{132}{33}\) = 4 hours

 

For every hour the train completes, 2 trains start in the opposite direction. 

 

Hence, the number of trains that travel from Fairy Land to Unicorn Village = 4 \(\times\) 2 = 8

 

Therefore, eight trains start from Fairy Land to Unicorn Village in four hours.
