Factors of 1646
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 1646, how they are used in real life, and tips to learn them quickly.
What are the Factors of 1646?
The numbers that divide 1646 evenly are known as factors of 1646. A factor of 1646 is a number that divides the number without remainder. The factors of 1646 are 1, 2, 823, and 1646. Negative factors of 1646: -1, -2, -823, and -1646. Prime factors of 1646: 2 and 823. Prime factorization of 1646: 2 × 823. The sum of factors of 1646: 1 + 2 + 823 + 1646 = 2472
How to Find Factors of 1646?
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 1646. Identifying the numbers that are multiplied to get the number 1646 is the multiplication method. Step 1: Multiply 1646 by 1, 1646 × 1 = 1646. Step 2: Check for other numbers that give 1646 after multiplying 2 × 823 = 1646 Therefore, the positive factor pairs of 1646 are: (1, 1646) and (2, 823). All these factor pairs result in 1646. 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 1646 by 1, 1646 ÷ 1 = 1646. Step 2: Continue dividing 1646 by the numbers until the remainder becomes 0. 1646 ÷ 1 = 1646 1646 ÷ 2 = 823 Therefore, the factors of 1646 are: 1, 2, 823, and 1646.
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 1646 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1. 1646 ÷ 2 = 823 823 ÷ 823 = 1 The prime factors of 1646 are 2 and 823. The prime factorization of 1646 is: 2 × 823.
Factor Tree
The factor tree is a graphical representation of breaking down any number into prime factors. The following step shows - Step 1: Firstly, 1646 is divided by 2 to get 823. Step 2: Now divide 823 by 823 to get 1. Here, 823 is the smallest prime number, that cannot be divided anymore. So, the prime factorization of 1646 is: 2 × 823. 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 1646: (1, 1646) and (2, 823). Negative factor pairs of 1646: (-1, -1646) and (-2, -823).
Common Mistakes and How to Avoid Them in Factors of 1646
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 factors for every number. Always remember to include 1 and the number itself. For example, in factors of 1646, 1 and 1646 are also factors.
Mistake 2
Missing Negative Factors
We have used to mention only positive factors every time. There are also negative factors, always check whether you have mentioned negative factors. For example, the factors of 1646 consist of -1, -2, -823, etc.
Mistake 3
Including the Fraction
Children might sometimes add fractions also as factors. Only whole numbers can be a factor. For example, thinking 1.5 as a factor, because 1646/1.5 = 1097.333, and it is not a whole number.
Mistake 4
Confusing Factors With Prime Numbers
Remember that factors can be any whole numbers, not only just primes. For example, thinking all the factors of 1646 are prime numbers. For example, 2 and 823 are the prime factors of 1646, but it has other factors like 1 and 1646.
Mistake 5
Mistake in Factorization
Children might skip the steps in factorization and end up writing wrong factors. For example, not breaking 1646 as 2 × 823 and missing all the key factors.
Factors of 1646 Examples
Problem 1
There are 4 friends and 1646 marbles. How will they divide it equally?
They will get 411 marbles each.
Explanation
To divide the marbles equally, we need to divide the total marbles with the number of friends. 1646/4 = 411.5
Problem 2
A rectangular field has a length of 823 meters and a total area of 1646 square meters. Find the width?
2 meters.
Explanation
To find the width of the field, we use the formula, Area = length × width 1646 = 823 × width To find the value of width, we need to shift 823 to the left side. 1646/823 = width Width = 2.
Problem 3
There are 823 gift bags and 1646 chocolates. How many chocolates will be in each bag?
Each bag will have 2 chocolates.
Explanation
To find the chocolates in each bag, divide the total chocolates with the bags. 1646/823 = 2
Problem 4
In a class, there are 1646 students, and 823 groups. How many students are there in each group?
There are 2 students in each group.
Explanation
Dividing the students with the total groups, we will get the number of students in each group. 1646/823 = 2
Problem 5
1646 books need to be arranged in 2 shelves. How many books will go on each shelf?
Each of the shelves has 823 books.
Explanation
Divide total books with shelves. 1646/2 = 823
