Factors of 491
Factors are the numbers that divide any given number evenly without remainder. In daily life, we use factors for tasks like sharing the items equally, arranging things, etc. In this topic, we will learn about the factors of 491, how they are used in real life, and tips to learn them quickly.
What are the Factors of 491?
The numbers that divide 491 evenly are known as factors of 491. A factor of 491 is a number that divides the number without remainder. The factors of 491 are 1 and 491. Negative factors of 491: -1 and -491. Prime factors of 491: 491. Prime factorization of 491: 491 (since 491 is a prime number). The sum of the factors of 491: 1 + 491 = 492
How to Find Factors of 491?
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 pairs of numbers that are multiplied to give 491. Since 491 is a prime number, the only multiplication factor pairs are: Step 1: Multiply 491 by 1, 491 × 1 = 491. Therefore, the positive factor pairs of 491 are: (1, 491). 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 491 by 1, 491 ÷ 1 = 491. Step 2: Check if 491 is divisible by any number other than 1 and itself. Since it is not, the factors of 491 are: 1 and 491.
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: Since 491 is a prime number, it cannot be broken down further. The prime factors of 491 are 491 itself.
Factor Tree
The factor tree is the graphical representation of breaking down any number into prime factors. The following step shows - Step 1: Since 491 is a prime number, it cannot be broken into a factor tree beyond (491). So, the prime factorization of 491 is: 491. 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 491: (1, 491). Negative factor pairs of 491: (-1, -491).
Common Mistakes and How to Avoid Them in Factors of 491
Mistakes are common while finding factors. We can identify and correct those mistakes using the following common mistakes and the ways to avoid them.
Mistake 1
Forgetting the number itself and 1 is a factor
Children might forget to add the given number itself and 1 as a factor. The number itself and 1 are the factors for every number. Always remember to include 1 and the number itself. For example, in factors of 491, 1 and 491 is also a factor.
Factors of 491 Examples
Problem 1
There are 491 apples and 1 basket. How will they be divided?
All 491 apples will go into the basket.
Explanation
To divide the apples equally, we need to divide the total apples by the number of baskets. 491/1 = 491
Problem 2
A wall is 491 meters long. If each section is 1 meter long, how many sections are there?
There are 491 sections.
Explanation
To find the number of sections, we use the formula, Total length = sections × section length 491 = sections × 1 Sections = 491
Problem 3
There are 491 people and 491 seats. How many people will share each seat?
Each seat will have 1 person.
Explanation
To find the number of people per seat, divide the total number of people by the seats. 491/491 = 1
Problem 4
A company produces 491 units in one day. If each unit requires 1 hour to make, how many hours are needed to produce all units?
491 hours are needed.
Explanation
Dividing the total production hours by the units gives the hours required: 491/1 = 491
Problem 5
491 books need to be stored in 1 library section. How many books will go in that section?
All 491 books will go in that library section.
Explanation
Divide total books by sections: 491/1 = 491
