What are the Factors of 1919?
The numbers that divide 1919 evenly are known as factors of 1919.
A factor of 1919 is a number that divides the number without a remainder.
The factors of 1919 are 1, 11, 17, 101, 187, and 1919.
Negative factors of 1919: -1, -11, -17, -101, -187, and -1919.
Prime factors of 1919: 11 and 17.
Prime factorization of 1919: 11 × 17 × 101.
The sum of factors of 1919: 1 + 11 + 17 + 101 + 187 + 1919 = 2236
How to Find Factors of 1919?
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 1919. Identifying the numbers which are multiplied to get the number 1919 is the multiplication method.
Step 1: Multiply 1919 by 1, 1919 × 1 = 1919.
Step 2: Check for other numbers that give 1919 after multiplying 11 × 17 × 101 = 1919
Therefore, the positive factor pairs of 1919 are: (1, 1919), (11, 17, 101). All these factor pairs result in 1919.
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 1919 by 1, 1919 ÷ 1 = 1919.
Step 2: Continue dividing 1919 by the numbers until the remainder becomes 0.
1919 ÷ 1 = 1919
1919 ÷ 11 = 174.45 (not a factor)
1919 ÷ 17 = 113
1919 ÷ 101 = 19
Therefore, the factors of 1919 are: 1, 11, 17, 101, 187, and 1919.
Prime Factors and Prime Factorization
The factors can be found by dividing them with prime numbers. We can find the prime factors using the following methods:
- Using prime factorization
- Using a factor tree
Using Prime Factorization: In this process, prime factors of 1919 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.
1919 ÷ 11 = 174.45 (not a factor)
1919 ÷ 17 = 113
113 ÷ 101 = 1.118 (not a factor)
The prime factors of 1919 are 11, 17, and 101.
The prime factorization of 1919 is: 11 × 17 × 101.
Factor Tree
The factor tree is the graphical representation of breaking down any number into prime factors. The following step shows
Step 1: Firstly, 1919 is divided by 11 to get 174.45 (not a factor).
Step 2: Divide 1919 by 17 to get 113.
Step 3: Now divide 113 by 101 to get 1.118 (not a factor). 1919 is composed of the smallest prime factors, 11, 17, and 101. So, the prime factorization of 1919 is: 11 × 17 × 101.
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 1919: (1, 1919), (11, 17, 101).
Negative factor pairs of 1919: (-1, -1919), (-11, -17, -101).
Common Mistakes and How to Avoid Them in Factors of 1919
Mistakes are common while finding factors. We can identify and correct those mistakes using the following common mistakes and 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 1919, 1 and 1919 are also factors.
Mistake 2
Missing Negative Factors
We often mention only positive factors. There are also negative factors, always check whether you have mentioned negative factors.
For example, the factors of 1919 consist of -1, -11, -17, 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 1919/1.5 is not a whole number.
Mistake 4
Confusing Factors With Prime Numbers
Remember that factors can be any whole number, not only just primes.
For example, thinking all the factors of 1919 are prime numbers. For example, 11, 17, and 101 are the prime factors of 1919, but it has other factors like 1 and 1919.
Mistake 5
Mistake in Factorization
Children might skip the steps in factorization and end up writing wrong factors.
For example, not breaking 1919 as 11 × 17 × 101 and missing all the key factors.
