**What are the factors of 30?**

The factors of 30 are the whole numbers that divide 30 without leaving a remainder. The factors of 30 are: 1, 2, 3, 5, 6, 10, 15, and 30.

**Finding the Factors of 30**

- Start with 1: Every number has 1 and itself as factors. So, 1 is always the first factor.
- The Number Itself: As mentioned earlier, every number is a factor of itself, so 30 is also a factor of 30.
- Divide by Small Numbers: Now, let’s find the other factors. We start by dividing 30 by the smallest prime numbers – 2, 3, 5, 7, 11, etc.
- Divide by 2: 30 ÷ 2 = 15. Since 15 is not a whole number, 2 is not a factor of 30.
- Divide by 3: 30 ÷ 3 = 10. Again, 10 is a whole number, so 3 is a factor of 30.
- Divide by 5: 30 ÷ 5 = 6. 6 is a whole number, so 5 is a factor of 30.
- Continue Dividing: Now, we can stop here because continuing to divide by other numbers will lead to decimals, which we don’t need for finding factors.

**Prime Factorization**

Prime factorization is the process of expressing a number as a product of its prime factors. Prime factors are prime numbers that divide the original number without leaving a remainder. Let’s find the prime factorization of 30:

- Step 1: Divide by the smallest prime number, which is 2.

30 ÷ 2 = 15

- Step 2: Divide 15 by the smallest prime number again, which is 3.

15 ÷ 3 = 5

- Step 3: We have reached a prime number (5), so we stop.

The prime factorization of 30 is: 30 = 2 × 3 × 5

This means that 2, 3, and 5 are the prime factors of 30, and when you multiply them together, you get the original number 30.

**Multiples Of 30**

To find the multiples of 30, we simply multiply 30 by different whole numbers. Here are the multiples of 30:

1 times 30 = 30

2 times 30 = 60

3 times 30 = 90

4 times 30 = 120

5 times 30 = 150

6 times 30 = 180

7 times 30 = 210

8 times 30 = 240

9 times 30 = 270

10 times 30 = 300

And so on. The multiples of 30 are infinite and are obtained by multiplying 30 by any positive whole number.

**Frequently Asked Questions (FAQs) **

**Q: What are the proper factors of 30?**

A: The proper factors of 30 are the factors of 30 that are not 1 or 30 themselves. These are 2, 3, 5, 6, 10, and 15.

**Q: How do I find the factors of a number?**

A: To find the factors of a number, start by dividing the number by the smallest prime numbers (2, 3, 5, etc.), and continue dividing until no further whole number division is possible. The results of these divisions are the factors of the number.

**Q: What are prime factors?**

A: Prime factors are factors that are prime numbers. Prime numbers are numbers greater than 1 that have only two distinct factors: 1 and the number itself. For example, the prime factors of 30 are 2, 3, 5

**Q: What is the relationship between factors and multiples?**

A: Factors and multiples are related: a factor of a number is also a divisor, and a multiple of a number is a result of multiplying that number. For example, in the case of 6, the factors are 1, 2, 3, and 6, while the multiples are 6, 12, 18, etc.

**Q: How many factors does 30 have?**

A: 30 has 8 factors. These are 1, 2, 3, 5, 6, 10, 15, and 30

**Q: How can I use factors of 30 in everyday life?**

A: Understanding factors can be helpful in various everyday scenarios, such as dividing items into equal groups, calculating common denominators for fractions, or finding the optimal number of people for a task, among other mathematical problems., 10, 15, and 30.

**Q: Is 30 a perfect number?**

A: No, 30 is not a perfect number. A perfect number is one whose factors (excluding the number itself) add up to the number itself. For example, the factors of 30 (excluding 30 itself)

**Q: What is the least common multiple (LCM)?**

A: The least common multiple (LCM) of two or more numbers is the smallest multiple that is common to all of those numbers. LCM is used in various mathematical operations, such as adding and subtracting fractions with different denominators.

**Q: What is the greatest common divisor (GCD) or greatest common factor (GCF)?**

A: The greatest common divisor (GCD) or greatest common factor (GCF) of two or more numbers is the largest number that can divide all the given numbers without leaving any remainder. GCD is used in simplifying fractions and solving certain mathematical problems.

**Conclusion**

Finding factors involves dividing the number by various whole numbers until no further whole number division is possible. The process helps us understand the divisors and the structure of the number.
