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 68, how they are used in real life, and tips to learn them quickly.

What are the Factors of 68?

The numbers that divide 68 evenly are known as factors of 68. A factor of 68 is a number that divides the number without remainder. The factors of 68 are 1, 2, 4, 17, 34, and 68. Negative factors of 68: -1, -2, -4, -17, -34, and -68. Prime factors of 68: 2 and 17. Prime factorization of 68: 2 × 34 = 2 × (2 × 17) = 2² × 17. The sum of factors of 68: 1 + 2 + 4 + 17 + 34 + 68 = 126

How to Find Factors of 68?

Factors can be found using different methods. Mentioned below are some commonly used methods: Finding factors using multiplication Finding factors using division method 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 68. Identifying the numbers that are multiplied to get the number 68 is the multiplication method. Step 1: Multiply 68 by 1, 68 × 1 = 68. Step 2: Check for other numbers that give 68 after multiplying 2 × 34 = 68 4 × 17 = 68 Therefore, the positive factor pairs of 68 are: (1, 68), (2, 34), (4, 17). All these factor pairs result in 68. 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 68 by 1, 68 ÷ 1 = 68. Step 2: Continue dividing 68 by the numbers until the remainder becomes 0. 68 ÷ 1 = 68 68 ÷ 2 = 34 68 ÷ 4 = 17 Therefore, the factors of 68 are: 1, 2, 4, 17, 34, 68.

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 Using factor tree Using Prime Factorization: In this process, prime factors of 68 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1. 68 ÷ 2 = 34 34 ÷ 2 = 17 17 ÷ 17 = 1 The prime factors of 68 are 2 and 17. The prime factorization of 68 is: 2² × 17.

Factor Tree

The factor tree is the graphical representation of breaking down any number into prime factors. The following step shows - Step 1: Firstly, 68 is divided by 2 to get 34. Step 2: Now divide 34 by 2 to get 17. Here, 17 is the smallest prime number and cannot be divided anymore. So, the prime factorization of 68 is: 2² × 17. 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 68: (1, 68), (2, 34), (4, 17). Negative factor pairs of 68: (-1, -68), (-2, -34), (-4, -17).

Problem 2

A garden plot is rectangular, the length of the plot is 4 meters and the total area is 68 square meters. Find the width?

Okay, lets begin

17 meters.

Explanation

To find the width of the plot, we use the formula, Area = length × width 68 = 4 × width To find the value of width, we need to shift 4 to the left side. 68/4 = width Width = 17.
