The prime factorization of 60 reveals which numbers are its factors. Let's explore this concept in detail.

Understanding Prime Factorization

Prime factorization is the process of breaking down a number into its prime number components. A prime number is a whole number greater than 1 that has only two divisors: 1 and itself. Examples include 2, 3, 5, 7, 11, and so on.

To find the prime factorization of 60, we can use a factor tree:

• Start with 60.
• Find two factors of 60 (e.g., 6 and 10).
• Continue breaking down each factor until you only have prime numbers.

A factor tree for 60 might look like this:

      60
     /  \
    6    10
   / \   / \
  2  3  2   5 

This shows that the prime factorization of 60 is 2 x 2 x 3 x 5, or 2² x 3 x 5.

Identifying Factors from the Prime Factorization

Any number that is a product of these prime factors (2, 2, 3, and 5) is a factor of 60. This includes:

• 2: A prime factor itself.
• 3: A prime factor itself.
• 4 (2 x 2): A combination of prime factors.
• 5: A prime factor itself.
• 6 (2 x 3): A combination of prime factors.
• 10 (2 x 5): A combination of prime factors.
• 12 (2 x 2 x 3): A combination of prime factors.
• 15 (3 x 5): A combination of prime factors.
• 20 (2 x 2 x 5): A combination of prime factors.
• 30 (2 x 3 x 5): A combination of prime factors.
• 60 (2 x 2 x 3 x 5): The number itself, always a factor.

And of course, 1 is also a factor of every number, including 60.

Therefore, any number you can create by multiplying some or all of the prime factors (2, 2, 3, and 5) will be a factor of 60.

Common Questions about Prime Factorization of 60

Q: How do I find all the factors of 60?

A: The most efficient way is to find the prime factorization first (2² x 3 x 5). Then systematically create combinations of these prime factors to find all possible factors.

Q: Is there a specific number that's always a factor in a prime factorization?

A: Yes, 1 is a factor of every number. Each prime factor is also a factor.

Q: What are some real-world applications of prime factorization?

A: Prime factorization has applications in cryptography (RSA encryption), simplifying fractions, and solving various mathematical problems.

By understanding prime factorization, we can easily identify all the factors of a number like 60. This fundamental concept is crucial for various mathematical applications.
