Factors are the numbers that divide any given number evenly without 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 98, how they are used in real life, and the tips to learn them quickly.

What are the Factors of 98?

The numbers that divide 98 evenly are known as factors of 98. A factor of 98 is a number that divides the number without remainder. The factors of 98 are 1, 2, 7, 14, 49, and 98.

Negative factors of 98: -1, -2, -7, -14, -49, and -98.

Prime factors of 98: 2 and 7.

Prime factorization of 98: 2 × 7².

The sum of factors of 98: 1 + 2 + 7 + 14 + 49 + 98 = 171

How to Find Factors of 98?

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

Finding Factors Using Multiplication

To find factors using multiplication, we need to identify the pairs of numbers that are multiplied to give 98. Identifying the numbers which are multiplied to get the number 98 is the multiplication method.

Step 1: Multiply 98 by 1, 98 × 1 = 98.

Step 2: Check for other numbers that give 98 after multiplying 2 × 49 = 98

7 × 14 = 98

Therefore, the positive factor pairs of 98 are: (1, 98), (2, 49), (7, 14).

All these factor pairs result in 98. For every positive factor, there is a negative factor.

Finding Factors Using Division Method

Dividing the given numbers with 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 98 by 1, 98 ÷ 1 = 98.

Step 2: Continue dividing 98 by the numbers until the remainder becomes 0.

98 ÷ 1 = 98

98 ÷ 2 = 49

98 ÷ 7 = 14

Therefore, the factors of 98 are: 1, 2, 7, 14, 49, 98.

Prime Factors and Prime Factorization

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

Using Prime Factorization: In this process, prime factors of 98 divide the number to break it down into the multiplication form of prime factors till the remainder becomes 1.

98 ÷ 2 = 49

49 ÷ 7 = 7

7 ÷ 7 = 1

The prime factors of 98 are 2 and 7. The prime factorization of 98 is: 2 × 7².

Factor Tree

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

Step 1: Firstly, 98 is divided by 2 to get 49.

Step 2: Now divide 49 by 7 to get 7.

Step 3: Divide 7 by 7 to get 1. Here, we reach 1, and all the factors are prime numbers. So, the prime factorization of 98 is: 2 × 7².

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 98: (1, 98), (2, 49), (7, 14).
  • Negative factor pairs of 98: (-1, -98), (-2, -49), (-7, -14).

Common Mistakes and How to Avoid Them in Factors of 98

Problem 1

There are 49 apples and 98 chocolates. How will they distribute the chocolates equally among the apples?

Okay, lets begin

They will get 2 chocolates each.

Explanation

To distribute the chocolates equally,

we need to divide the total chocolates by the number of apples.

98/49 = 2

Problem 2

A rectangular garden has a length of 7 meters and a total area of 98 square meters. Find the width?

Okay, lets begin

14 meters.

Explanation

To find the width of the garden, we use the formula,

Area = length × width

98 = 7 × width

To find the value of width, we need to shift 7 to the left side.

98/7 = width

Width = 14.

Problem 3

There are 14 baskets, and 98 mangoes. How many mangoes will be in each basket?

Okay, lets begin

Each basket will have 7 mangoes.

Explanation

To find the mangoes in each basket,

divide the total mangoes by the baskets.

98/14 = 7

Problem 4

In a class, there are 98 students, and 7 groups. How many students are there in each group?

Okay, lets begin

There are 14 students in each group.

Explanation

Dividing the students by the total groups,

we will get the number of students in each group.

98/7 = 14

Well explained 👍

Problem 5

98 books need to be arranged on 2 shelves. How many books will go on each shelf?

Okay, lets begin

Each of the shelves has 49 books.

Explanation

Divide total books by shelves.
