Factors can be found using different methods. Mentioned below are some commonly used methods

1. Finding factors using multiplication
2. Finding factors using division method
3. Prime factors and Prime factorization

To find factors using multiplication, we need to identify the pairs of numbers that are multiplied to give 90000. Identifying the numbers which are multiplied to get the number 90000 is the multiplication method.

Step 1: Multiply 90000 by 1, 90000 × 1 = 90000.

Step 2: Check for other numbers that give 90000 after multiplying

2 × 45000 = 90000

3 × 30000 = 90000

4 × 22500 = 90000

5 × 18000 = 90000 ... (continue for other pairs)

Therefore, some of the positive factor pairs of 90000 are: (1, 90000), (2, 45000), (3, 30000), (4, 22500), (5, 18000), and so on. For every positive factor, there is a negative factor.

Dividing the given numbers with whole numbers until the remainder becomes zero and listing out the numbers which result as whole numbers as factors. Factors can be calculated by following the simple division method -

Step 1: Divide 90000 by 1, 90000 ÷ 1 = 90000.

Step 2: Continue dividing 90000 by the numbers until the remainder becomes 0.

90000 ÷ 1 = 90000

90000 ÷ 2 = 45000

90000 ÷ 3 = 30000

90000 ÷ 4 = 22500

90000 ÷ 5 = 18000 ... (continue for other divisions)

Therefore, the factors of 90000 include numbers such as 1, 2, 3, 4, 5, 6, 8, 9, 10, and so on.

The factors can be found by dividing with prime numbers. We can find the prime factors using the following methods:

• Using prime factorization
• Using factor tree

Using Prime Factorization: In this process, prime factors of 90000 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.

90000 ÷ 2 = 45000

45000 ÷ 2 = 22500

22500 ÷ 2 = 11250

11250 ÷ 2 = 5625

5625 ÷ 3 = 1875

1875 ÷ 3 = 625

625 ÷ 5 = 125

125 ÷ 5 = 25

25 ÷ 5 = 5

5 ÷ 5 = 1

The prime factors of 90000 are 2, 3, and 5. The prime factorization of 90000 is: 2⁴ × 3² × 5⁴.

The factor tree is the graphical representation of breaking down any number into prime factors. The following step shows -

Step 1: Firstly, 90000 is divided by 2 to get 45000.

Step 2: Now divide 45000 by 2 to get 22500.

Step 3: Then divide 22500 by 2 to get 11250.

Step 4: Divide 11250 by 2 to get 5625.

Step 5: Divide 5625 by 3 to get 1875.

Step 6: Divide 1875 by 3 to get 625.

Step 7: Divide 625 by 5 to get 125.

Step 8: Divide 125 by 5 to get 25.

Step 9: Divide 25 by 5 to get 5. Here, 5 is the smallest prime number that cannot be divided anymore. So, the prime factorization of 90000 is: 2⁴ × 3² × 5⁴.

Factor Pairs: Two numbers that are multiplied to give a specific number are called factor pairs. Both positive and negative factors constitute factor pairs.
