Factors of 647
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 647, how they are used in real life, and tips to learn them quickly.
What are the Factors of 647?
The numbers that divide 647 evenly are known as factors of 647. A factor of 647 is a number that divides the number without remainder. The factors of 647 are 1 and 647.
Negative factors of 647: -1 and -647.
Prime factors of 647: 647 (since it is a prime number).
Prime factorization of 647: 647.
The sum of factors of 647: 1 + 647 = 648
How to Find Factors of 647?
Factors can be found using different methods. Mentioned below are some commonly used methods:
- Finding factors using multiplication
- Finding factors using the 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 647. Identifying the numbers which are multiplied to get the number 647 is the multiplication method.
Step 1: Multiply 647 by 1, 647 × 1 = 647.
Since 647 is a prime number, no other positive factor pairs exist apart from (1, 647). 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 in whole numbers as factors. Factors can be calculated by following a simple division method:
Step 1: Divide 647 by 1, 647 ÷ 1 = 647.
Step 2: Since 647 is a prime number, it will not be divisible by any other number except 647. Therefore, the factors of 647 are: 1 and 647.
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
- Using factor tree
Using Prime Factorization: In this process, prime factors of 647 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.
Since 647 is a prime number, it cannot be broken down further. The prime factorization of 647 is: 647.
Factor Tree
The factor tree is the graphical representation of breaking down any number into prime factors. Since 647 is a prime number, it cannot be broken down further using a factor tree. The prime factorization of 647 is: 647.
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 647: (1, 647).
- Negative factor pairs of 647: (-1, -647).
Common Mistakes and How to Avoid Them in Factors of 647
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 647, 1 and 647 are also factors.
Factors of 647 Examples
Problem 1
A group of 647 birds needs to be divided into 1 aviary. How will they be arranged?
All 647 birds will be in the aviary.
Explanation
To arrange the birds, we need to divide the total number by the number of aviaries. 647/1 = 647
Problem 2
A museum has a single exhibit with 647 artifacts. How many artifacts are in each exhibit?
647 artifacts.
Explanation
To find the number of artifacts in each exhibit,
we use the formula: Total artifacts = number of exhibits × artifacts per exhibit
647 = 1 × artifacts per exhibit Artifacts per exhibit = 647/1 = 647.
Problem 3
There is 1 shelf that can hold 647 books. How many books can each shelf hold?
Each shelf can hold 647 books.
Explanation
To find the books on each shelf, divide the total books by the number of shelves.
647/1 = 647
Problem 4
A marathon has 647 participants in 1 group. How many participants are there in each group?
There are 647 participants in the group.
Explanation
Dividing the participants by the total groups, we find the number of participants in each group.
647/1 = 647
Problem 5
A single truck can carry 647 units of cargo. How many units does each truck carry?
Each truck carries 647 units.
Explanation
To find the cargo per truck, divide the total cargo by the number of trucks.
647/1 = 647
