Introduction

Prime factorization is a fundamental concept in mathematics that involves breaking down a composite number into its prime factors. In this article, we will explore the prime factorization of 1,260, a number that has various applications in mathematics, science, and engineering. We will use the concept of prime factorization to understand the properties and characteristics of 1,260, and provide a step-by-step guide on how to find its prime factors.

What is Prime Factorization?

Prime factorization is the process of expressing a composite number as a product of its prime factors. A prime factor is a prime number that divides the original number evenly. For example, the prime factorization of 12 is 2 × 2 × 3, because 2 and 3 are prime numbers that divide 12 evenly.

Why is Prime Factorization Important?

Prime factorization is an essential concept in mathematics because it helps us understand the properties and characteristics of numbers. By breaking down a composite number into its prime factors, we can:

Identify the prime factors of a number
Determine the number of divisors of a number
Find the greatest common divisor (GCD) of two numbers
Perform various mathematical operations, such as multiplication and division

Finding the Prime Factorization of 1,260

To find the prime factorization of 1,260, we will use the following steps:

Divide 1,260 by the smallest prime number, which is 2.
Continue dividing the result by 2 until we can no longer divide evenly.
Move on to the next prime number, which is 3, and repeat the process.
Continue dividing by prime numbers until we have factored out all the prime factors.

Let's apply these steps to find the prime factorization of 1,260:

Divide 1,260 by 2: 1,260 ÷ 2 = 630
Continue dividing by 2: 630 ÷ 2 = 315
Move on to the next prime number, which is 3: 315 ÷ 3 = 105
Continue dividing by prime numbers: 105 ÷ 3 = 35
Continue dividing by prime numbers: 35 ÷ 5 = 7

The Prime Factorization of 1,260

The prime factorization of 1,260 is:

2 × 2 × 3 × 3 × 5 × 7
