Factors of 1909
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 1909, how they are used in real life, and the tips to learn them quickly.
What are the Factors of 1909?
The numbers that divide 1909 evenly are known as factors of 1909.
A factor of 1909 is a number that divides the number without remainder.
The factors of 1909 are 1, 7, 272, and 1909.
Negative factors of 1909: -1, -7, -272, and -1909.
Prime factors of 1909: 7 and 272.
Prime factorization of 1909: 7 × 272.
The sum of factors of 1909: 1 + 7 + 272 + 1909 = 2189
How to Find Factors of 1909?
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 1909. Identifying the numbers which are multiplied to get the number 1909 is the multiplication method.
Step 1: Multiply 1909 by 1, 1909 × 1 = 1909.
Step 2: Check for other numbers that give 1909 after multiplying 7 × 272 = 1909
Therefore, the positive factor pairs of 1909 are: (1, 1909) and (7, 272). All these factor pairs result in 1909.
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 1909 by 1, 1909 ÷ 1 = 1909.
Step 2: Continue dividing 1909 by the numbers until the remainder becomes 0.
1909 ÷ 1 = 1909
1909 ÷ 7 = 272
Therefore, the factors of 1909 are: 1, 7, 272, 1909.
Prime Factors and Prime Factorization
The factors can be found by dividing it with a prime number. 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 1909 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.
1909 ÷ 7 = 272
272 ÷ 272 = 1
The prime factors of 1909 are 7 and 272.
The prime factorization of 1909 is: 7 × 272.
Factor Tree
The factor tree is the graphical representation of breaking down any number into prime factors. The following step shows
Step 1: Firstly, 1909 is divided by 7 to get 272.
Step 2: 272 is a factor itself, and division by 272 results in 1. So, the prime factorization of 1909 is: 7 × 272.
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 1909: (1, 1909) and (7, 272).
Negative factor pairs of 1909: (-1, -1909) and (-7, -272).
Common Mistakes and How to Avoid Them in Factors of 1909
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 1909, 1 and 1909 are also factors.
Mistake 2
Missing Negative Factors
We often mention only positive factors. There are also negative factors, so always check whether you have mentioned negative factors.
For example, the factors of 1909 consist of -1, -7, -272, etc.
Mistake 3
Including the Fraction
Children might sometimes add fractions as factors. Only whole numbers can be factors.
For example, thinking 2.5 as a factor because 1909/2.5 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 1909 are prime numbers.
For example, 7 is a prime factor of 1909, but it has other factors like 272.
Mistake 5
Mistake in Factorization
Children might skip the steps in factorization and end up writing wrong factors.
For example, not breaking 1909 as 7 × 272 and missing all the key factors.
Factors of 1909 Examples
Problem 1
There are 7 teams and 1909 total points scored in a tournament. How will they divide the points equally?
They will get 272 points each.
Explanation
To divide the points equally, we need to divide the total points by the number of teams.
1909/7 = 272
Problem 2
A book has 1909 pages. If a person reads 7 pages per day, how many days will it take to finish the book?
272 days.
