Factors are the numbers that divide any given number evenly without a remainder. In daily life, we use factors for tasks like sharing items equally, arranging things, etc. In this topic, we will learn about the factors of 142, how they are used in real life, and tips to learn them quickly.

What are the Factors of 142?

The numbers that divide 142 evenly are known as factors of 142. A factor of 142 is a number that divides the number without a remainder. The factors of 142 are 1, 2, 71, and 142.

Negative factors of 142: -1, -2, -71, and -142

Prime factors of 142: 2 and 71.

Prime factorization of 142: 2 × 71.

The sum of factors of 142: 1 + 2 + 71 + 142 = 216

How to Find Factors of 142?

Factors can be found using different methods. Mentioned below are some commonly used methods:

  1. Finding factors using multiplication
  2. Finding factors using the division method
  3. Prime factors and prime factorization

Finding Factors Using Multiplication

To find factors using multiplication, we need to identify the pairs of numbers that are multiplied to give 142. Identifying the numbers which are multiplied to get the number 142 is the multiplication method.

Step 1: Multiply 142 by 1, 142 × 1 = 142.

Step 2: Check for other numbers that give 142 after multiplying: 2 × 71 = 142

Therefore, the positive factor pairs of 142 are: (1, 142) and (2, 71). For every positive factor, there is a negative factor.

Finding Factors Using Division Method

Dividing the given numbers with the whole numbers until the remainder becomes zero and listing out the numbers which result as whole numbers as factors. Factors can be calculated by following a simple division method -

Step 1: Divide 142 by 1, 142 ÷ 1 = 142.

Step 2: Continue dividing 142 by the numbers until the remainder becomes 0.

142 ÷ 1 = 142

142 ÷ 2 = 71

Therefore, the factors of 142 are: 1, 2, 71, 142.

Prime Factors and Prime Factorization

The factors can be found by dividing with prime numbers. We can find the prime factors using the following methods:

Using Prime Factorization: In this process, prime factors of 142 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.

142 ÷ 2 = 71

71 ÷ 71 = 1

The prime factors of 142 are 2 and 71. The prime factorization of 142 is: 2 × 71.

Factor Tree

The factor tree is the graphical representation of breaking down any number into prime factors. The following steps show -

Step 1: Firstly, 142 is divided by 2 to get 71.

Step 2: Now divide 71 by 71 to get 1. So, the prime factorization of 142 is: 2 × 71.

Factor Pairs: Two numbers that are multiplied to give a specific number are called factor pairs. Both positive and negative factors constitute factor pairs.

  • Positive factor pairs of 142: (1, 142) and (2, 71).
  • Negative factor pairs of 142: (-1, -142) and (-2, -71).

Common Mistakes and How to Avoid Them in Factors of 142

Problem 1

There are 71 students and 142 pencils. How will they divide the pencils equally?

Okay, lets begin

They will get 2 pencils each.

Explanation

To divide the pencils equally, we need to divide the total pencils by the number of students

142/71 = 2

Well explained 👍

Problem 2

A rectangular field has a width of 2 meters and a total area of 142 square meters. Find the length.

Okay, lets begin

71 meters.

Explanation

To find the length of the field, we use the formula,

Area = length × width

142 = length × 2

To find the value of length, we need to shift 2 to the left side.

142/2 = length

Length = 71.
