How to Find Factors of 3780?
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 3780. Identifying the numbers which are multiplied to get the number 3780 is the multiplication method.
Step 1: Multiply 3780 by 1, 3780 × 1 = 3780.
Step 2: Check for other numbers that give 3780 after multiplying:
2 × 1890 = 3780
3 × 1260 = 3780
4 × 945 = 3780
5 × 756 = 3780
6 × 630 = 3780
Therefore, the positive factor pairs of 3780 are: (1, 3780), (2, 1890), (3, 1260), (4, 945), (5, 756), (6, 630), etc. 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 3780 by 1, 3780 ÷ 1 = 3780.
Step 2: Continue dividing 3780 by the numbers until the remainder becomes 0.
3780 ÷ 1 = 3780
3780 ÷ 2 = 1890
3780 ÷ 3 = 1260
3780 ÷ 4 = 945
3780 ÷ 5 = 756
Therefore, the factors of 3780 are: 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 63, 75, 90, 126, 150, 180, 189, 252, 315, 378, 630, 945, 1260, 1890, and 3780.
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 3780 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1
3780 ÷ 2 = 1890
1890 ÷ 2 = 945
945 ÷ 3 = 315
315 ÷ 3 = 105
105 ÷ 3 = 35
35 ÷ 5 = 7
7 ÷ 7 = 1
The prime factors of 3780 are 2, 3, 5, and 7.
The prime factorization of 3780 is: 2² × 3³ × 5 × 7.
Factor Tree
The factor tree is the graphical representation of breaking down any number into prime factors. The following step shows -
Step 1: Firstly, 3780 is divided by 2 to get 1890.
Step 2: Now divide 1890 by 2 to get 945.
Step 3: Then divide 945 by 3 to get 315.
Step 4: Now divide 315 by 3 to get 105.
Step 5: Divide 105 by 3 to get 35.
Step 6: Divide 35 by 5 to get 7. Here, 7 is the smallest prime number, that cannot be divided anymore. So, the prime factorization of 3780 is: 2² × 3³ × 5 × 7.
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 3780: (1, 3780), (2, 1890), (3, 1260), (4, 945), (5, 756), (6, 630), etc.
Negative factor pairs of 3780: (-1, -3780), (-2, -1890), (-3, -1260), (-4, -945), (-5, -756), (-6, -630), etc.
Common Mistakes and How to Avoid Them in Factors of 3780
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 3780, 1 and 3780 are also factors.
