Understanding the concept of prime factorization is essential for anyone interested in mathematics, as it helps to identify the building blocks of numbers and reveals the underlying structure of the number system. By mastering this concept, you will gain a deeper understanding of how numbers work and how they can be manipulated.
Before we dive into the prime factorization of 105, let's quickly review what prime factorization is. Prime factorization is the process of expressing a composite number as a product of prime numbers. A prime number is a positive integer that is divisible only by itself and 1, whereas a composite number is a positive integer that has at least one positive divisor other than 1 and itself.
Step-by-Step Guide to Prime Factorization of 105
The prime factorization of 105 involves a series of steps that help us identify the prime factors of the number. Here's a step-by-step guide to prime factorizing 105:
Step 1: Find the Smallest Prime Factor
The first step in prime factorizing 105 is to find the smallest prime factor of the number. We can start by dividing 105 by the smallest prime number, which is 2. However, 105 is an odd number, so we can immediately move on to the next prime number, which is 3.
Step 2: Divide by the Smallest Prime Factor
Now that we've identified 3 as a potential prime factor, we can divide 105 by 3. The result of this division is 35.
105 ÷ 3 = 35
Step 3: Find the Next Prime Factor
Next, we need to find the next prime factor of 105. Since we've already divided 105 by 3, we can focus on the result of that division, which is 35. We can start by dividing 35 by the smallest prime number, which is 2. However, 35 is an odd number, so we can move on to the next prime number, which is 5.
Step 4: Divide by the Next Prime Factor
Now that we've identified 5 as a potential prime factor, we can divide 35 by 5. The result of this division is 7.
35 ÷ 5 = 7
Step 5: Check if the Result is Prime
Now that we've divided 35 by 5, we need to check if the result, which is 7, is a prime number. Since 7 is indeed a prime number, we can conclude that the prime factorization of 105 is complete.
The prime factorization of 105 is:
105 = 3 × 5 × 7
