What are the Factors of 153?

The factors of 153 or the numbers which divide 153 exactly are:


1,3,9,17,51, and 153.

 

 

  • Negative factors of 153: -1,-3,-9,-17,-51,-153.

 

  • Prime factors of 153: 3,17

 

  • Prime factorization of 153: 32×17

 

  • The sum of factors of 153: 1+3+9+17+51+153= 234

How to Find the Factors of 153

For finding factors of 153, we will be learning these below-mentioned methods:

 

 

  • Multiplication Method

 

  • Division Method

 

  • Prime Factor and Prime Factorization

 

  • Factor Tree

Finding Factors using Multiplication Methods

This particular method often finds the pair of factors which, on multiplication together, produces 153.

 

Let us find the pairs which, on multiplication, yields 153.


1×153=153


3×51=153


9×17=153

 

Factors of 153 by multiplication method

 

So, factors of 153 are: 1,3,9,17,51, and 153.
 

Professor Greenline from BrightChamps

Finding Factors using Division Method

The division method finds the factors that evenly divides the given number 153. In this process, we have to divide 153 by all possible natural numbers less than 153 and check.


1,3,9,17,51, and 153 are the only factors that the number 153 has. So to verify the factors of 153 using the division method, we just need to divide 153 by each factor.


153/1 =153


153/3=51


153/9=17


153/17=9


153/51=3


153/153=1

Prime Factors and Prime Factorization

Prime Factorization is the easiest process to find prime factors. It decomposes 153 into a product of its prime integers.


Prime Factors of 153: 3,17.


Prime Factorization of 153: 32×17



 

Professor Greenline from BrightChamps

Factor tree

The number 153 is written on top and two branches are extended.


Fill in those branches with a factor pair of the number above, i.e., 153.


Continue this process until each branch ends with a prime factor (number).


The first two branches of the factor tree of 153 are 9 and 17. Similarly, for 9, we end up having two branches, each with prime factor 3.

Factor Pairs

 

  • Positive pair factors:   (1,153), (3,51), (9,17)

 

  • Negative pair factors:  (-1,-153), (-3,-51), (-9,-17).

Common Mistakes and How to Avoid Them in Factors of 153

Solving problems based on factors can, sometimes, lead to misconceptions among children. Let us check what the common errors are and how to avoid them.
 

Mistake 1

Red Cross Icon Indicating Mistakes to Avoid in This Math Topic

 Factors might be larger than the given number.
 

Green Checkmark Icon Indicating Correct Solutions in This Math Topic

Factors can never be larger than the given number, but multiples can be. You need to understand the concept that factors are integers which divide a given number perfectly, and multiples are the products we get when the original number is multiplied with different numbers.

Factors of 145 Examples

Ray, the Character from BrightChamps Explaining Math Concepts
Max, the Girl Character from BrightChamps

Problem 1

A man has 153 shirts and 51 ties. He wants to divide them equally among some poor people. What is the maximum number of people he can distribute?

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

Number of shirts: 153


Number of ties: 51


Factors of 153: 1,3,9,17,51,153


Factors of 51: 1,3,17


Common factors of 51 and 153: 1,3,17


Greatest common factor of 51 and 153: 17


So, there will be 17 people for distribution.


Answer: 17 people
 

Explanation

To divide equally, the maximum number of people can be found through the Greatest Common Factor. Here, we found the GCF, which is the answer.

Problem 2

Two airplanes leave the airport at the same time. One leaves every 17 hours and the other every 51 hours. When will they leave together again?

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

 Time-lapse of the 1st airplane: 17 hours


Time-lapse of the 2nd airplane: 51 hours


Prime factorization of 17:17×1


Prime factorization of 51: 3×17


LCM of 17 and 51: 17×3 = 51.


Both the airplanes will meet each other after 51 hours.


Answer: 51 hours
 

Explanation

To find the time again when two airplanes will meet, we have to find the LCM of the two given time-lapses. So, did prime factorization of both 17 and 51. The LCM is the product of the highest power of each factor.

Problem 3

Find the GCF of 153 and 51

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

 Factors of 153: 1,3,9,17,51,153


Factors of 51 : 1,3,17,51


Common factors of 153 and 51: 1, 3,17, 51


So, the Greatest Common Factor of 153 and 51 is 51.


Answer: 51
 

Explanation

We first listed out the factors of 153 and 51 and then found the common factors and then identified the greatest common factor from the common list.

 Prime factorization of 3: 3×1.


Prime factorization of 9: 32


Prime factorization of 17: 17×1


Prime factorization of 51: 3×17

 

LCM of 3,9,17 and 51: 3×17= 51


Answer: 51 is the smallest number which is divisible by 3,9,17,51.
 

Explanation

To find the smallest number which is divisible by 3,9,17,51, we need to find the LCM of these numbers.
