Factors of 521
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 521, how they are used in real life, and tips to learn them quickly.
What are the Factors of 521?
The numbers that divide 521 evenly are known as factors of 521.
A factor of 521 is a number that divides the number without remainder.
The factors of 521 are 1, 521.
Negative factors of 521: -1, -521.
Prime factors of 521: 521 (521 is a prime number).
Prime factorization of 521: 521 × 1.
The sum of factors of 521: 1 + 521 = 522
How to Find Factors of 521?
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 521. Identifying the numbers which are multiplied to get the number 521 is the multiplication method.
Step 1: Multiply 521 by 1, 521 × 1 = 521.
Step 2: Check for other numbers that give 521 after multiplying. Since 521 is a prime number, it has no other multiplication pairs.
Therefore, the positive factor pair of 521 is: (1, 521). 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 521 by 1, 521 ÷ 1 = 521.
Step 2: Continue dividing 521 by the numbers until the remainder becomes 0.
521 ÷ 1 = 521
521 ÷ 521 = 1
Since 521 is a prime number, no other whole numbers divide it evenly.
Therefore, the factors of 521 are: 1, 521.
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, 521 is already a prime number, so it cannot be broken down further into other prime factors.
The prime factorization of 521 is 521 × 1.
Factor Tree
The factor tree is the graphical representation of breaking down any number into prime factors. Since 521 is a prime number, it cannot be broken down further using a factor tree. Therefore, the prime factorization of 521 is simply 521 × 1.
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 pair of 521: (1, 521).
Negative factor pair of 521: (-1, -521).
Common Mistakes and How to Avoid Them in Factors of 521
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 521, 1 and 521 are factors.
