What is Factorization?

Factorization is a mathematical process that involves breaking down a number or expression into its prime factors. In other words, it is the process of expressing a number as a product of its prime numbers. This concept is crucial in mathematics, as it helps us understand the properties and behavior of numbers.

Why is Factorization Important?

Factorization is an essential concept in mathematics, and it has numerous applications in various fields, including algebra, geometry, and number theory. It helps us understand the properties of numbers, such as their divisibility, primality, and uniqueness. Additionally, factorization is used in cryptography, coding theory, and computer science.

Prime Numbers and Factorization

A prime number is a positive integer that is divisible only by itself and 1. For example, 2, 3, 5, and 7 are prime numbers. Prime numbers are the building blocks of all other numbers, and they play a crucial role in factorization.

Writing 360 as a Product of its Prime Factors

Now, let's focus on writing 360 as a product of its prime factors using factorization. To do this, we need to find the prime factors of 360.

Step 1: Find the Prime Factors of 360

To find the prime factors of 360, we can start by dividing it by the smallest prime number, which is 2.

360 ÷ 2 = 180

Next, we can divide 180 by 2 again.

180 ÷ 2 = 90

We can continue this process until we reach a number that is not divisible by 2.

90 ÷ 2 = 45

Now, we can divide 45 by the next prime number, which is 3.

45 ÷ 3 = 15

We can continue this process until we reach a number that is not divisible by 3.

15 ÷ 3 = 5

Now, we have reached a prime number, which is 5. We can stop here, as 5 is a prime number.

Step 2: Write 360 as a Product of its Prime Factors

Now that we have found the prime factors of 360, we can write it as a product of its prime factors.

360 = 2 × 2 × 2 × 3 × 3 × 5

Simplifying the Expression

We can simplify the expression by combining the repeated prime factors.

360 = 2^3 × 3^2 × 5

Conclusion

In this article, we have learned about the concept of factorization and how to write 360 as a product of its prime factors using factorization. We have seen that factorization is an essential concept in mathematics, and it has numerous applications in various fields. By understanding the properties of numbers and their prime factors, we can solve complex mathematical problems and make new discoveries.
