There are two main ways to factorize 180:

**Prime Factorization:**

This involves breaking down 180 into its most basic building blocks, which are prime numbers. Prime numbers are only divisible by 1 and themselves.

**Steps:**

- Divide 180 by the smallest prime number that divides it evenly, which is 2. You get 90.
- Divide 90 by 2 again. You get 45.
- Divide 45 by 3. You get 15.
- Divide 15 by 3 again. You get 5.

**Result:**

180 = 2 x 2 x 3 x 3 x 5

This represents the prime factorization of 180, showing that it can be formed by multiplying two 2s, two 3s, and one 5.

**Factor Pairs:**

This involves finding all pairs of numbers that multiply to 180.

**Examples:**

- 1 x 180

- The sum of all the factors of 180 (including 1 and itself) is 465, called the aliquot sum.

**How to Find the Factors of 180?**

**Here are two methods to find the factors of 180, accompanied by equations to illustrate the process:**

**Method 1: Prime Factorization**

**Break down 180 into its prime factors:**- 180 ÷ 2 = 90
- 90 ÷ 2 = 45
- 45 ÷ 3 = 15
- 15 ÷ 3 = 5

**Express the prime factorization as a product:**- 180 = 2 × 2 × 3 × 3 × 5

**Generate factor pairs from the prime factors:**- Combine the prime factors in different ways to create factor pairs:
- 1 × 180 = 180
- 2 × 90 = 180
- 3 × 60 = 180
- 4 × 45 = 180 … (and so on, using combinations of the prime factors)

- Combine the prime factors in different ways to create factor pairs:

**Method 2: Trial Division**

**Start with 1 and try dividing 180 by successive positive integers:**- 180 ÷ 1 = 180
- 180 ÷ 2 = 90
- 180 ÷ 3 = 60
- 180 ÷ 4 = 45
- … (continue until reaching the square root of 180, which is approximately 13.42)

**List the divisors and their corresponding quotients as factor pairs:**- 1 × 180
- 2 × 90
- 3 × 60
- 4 × 45
- 5 × 36
- … (and so on, until the quotients start repeating)

**Prime Factorization of 180:**

**The prime factorization of 180 is 2^2 × 3^2 × 5.**

Here’s how we arrive at this factorization:

**Start dividing 180 by the smallest prime number that divides it evenly, which is 2:**- 180 ÷ 2 = 90

**Divide 90 by 2 again:**- 90 ÷ 2 = 45

**Now try dividing 45 by the next smallest prime, 3:**- 45 ÷ 3 = 15

**Divide 15 by 3 again:**- 15 ÷ 3 = 5

**Since 5 is itself a prime number, we’ve reached the end of the factorization process.****Expressing this process as a series of divisions:**- 180 ÷ 2 ÷ 2 ÷ 3 ÷ 3 = 5

**Rewriting it as a product of prime factors:**- 180 = 2 × 2 × 3 × 3 × 5

Therefore, the prime factorization of 180 is 2^2 × 3^2 × 5, indicating that it can be formed by multiplying two 2s, two 3s, and one 5.
