Notes:
- A factor of a number is any number that can divide evenly into that number.
- 4500 has 36 positive factors and 36 negative factors, for a total of 72 factors.
- The prime factorization of 4500 is 2² * 3² * 5³. This means that the smallest prime numbers that can be multiplied together to make 4500 are 2, 3, and 5.
How to Find the Factors of 4500?
Finding the factors of 4500 involves understanding what a factor is and then using different methods to identify them. Here are two different approaches you can take:
1. Listing out all factors:
- Definition: A factor of a number is any number that divides evenly into that number with no remainder.
- Method: Start with 1 (as any number divides by 1) and progressively increase the divisor up to the number itself. For each divisor, check if it divides 4500 evenly with no remainder. If it does, it’s a factor. Write down all the factors you find.
2. Prime factorization:
- Definition: Prime factorization is breaking down a number into its prime factors, which are the smallest prime numbers that can be multiplied together to get the original number.
- Method: 1. Divide 4500 by the smallest prime number (2). Continue dividing by 2 as long as possible.
- When you reach an odd number, find the next smallest prime number (3) and repeat the division process.
- Keep dividing by increasingly larger prime numbers until you’re left with 1.
- Write down the exponents of each prime number used in the division process. These exponents represent the number of times each prime factor appears in the original number.
- Multiply the prime factors raised to their respective exponents. This should give you 4500.
By following either of these methods, you will find all the factors of 4500.
Here are some additional details about the factors of 4500:
- 4500 has a total of 36 factors (including 1 and itself).
- Its prime factorization is 2^2 * 3^2 * 5^3.
- It has 18 even factors and 18 odd factors.
- Its largest factor is 4500 itself.
Factors of 4500 by Prime Factorization
To find the prime factorization of 4500, you can start by dividing it by prime numbers until you can no longer divide evenly. Here’s the step-by-step process:
- 4500 ÷ 2 = 2250
- 2250 ÷ 2 = 1125
- 1125 ÷ 3 = 375
- 375 ÷ 3 = 125
- 125 ÷ 5 = 25
- 25 ÷ 5 = 5
- 5 ÷ 5 = 1
Now, combine the prime factors:
4500 = 2^2 * 3^2 * 5^3
So, the prime factorization of 4500 is 2^2 * 3^2 * 5^3.
Solved Examples on the Factors of 4500
Here are some solved examples involving the factors of 4500:
Example 1: Finding factors using prime factorization
- Find the prime factorization of 4500: 2^2 * 3^2 * 5^3
- Form factors by combining prime factors in different ways:
- 2 * 2 * 3 * 3 * 5 * 5 = 900
- 2 * 3 * 5 * 5 * 5 = 750
- 2^2 * 3 * 5 = 60
- 3 * 3 * 5^2 = 225
Example 2: Determining if a number is a factor
- Is 180 a factor of 4500?
- Yes, because 4500 ÷ 180 = 25, a whole number (no remainder).
Example 3: Counting factors
- How many factors does 4500 have?
- Use the prime factorization: 4500 = 2^2 * 3^2 * 5^3
- Add 1 to each exponent and multiply the results: (2+1)(2+1)(3+1) = 36 factors
