2. Steps to find factors of 900 using Prime Factorization

A prime number is a number that has exactly two factors, 1 and the number itself. Prime factorization of a number means breaking down of the number into the form of products of its prime factors.

There are two different methods that can be used for the prime factorization.

Method 1: Division Method

To find the primefactors of 900 using the division method, follow these steps:

  • Step 1. Start dividing 900 by the smallest prime number, i.e., 2, 3, 5, and so on. Find the smallest prime factor of the number.
  • Step 2. After finding the smallest prime factor of the number 900, which is 2. Divide 900 by 2 to obtain the quotient (450).
    900 ÷ 2 = 450
  • Step 3. Repeat step 1 with the obtained quotient (450).
    450 ÷ 2 = 225
    225 ÷ 3 = 75
    75 ÷ 3 = 25
    25 ÷ 5 = 5
    5 ÷ 5 = 1

So, the prime factorization of 900 is, 900 = 2 x 2 x 3 x 3 x 5 x 5.

Method 2: Factor Tree Method

We can follow the same procedure using the factor tree of 900 as shown below:

So, the prime factorization of 900 is, 900 = 2 x 2 x 3 x 3 x 5 x 5.

3. Find factors of 900 in Pairs

Pair factors of a number are any two numbers which, which on multiplying together, give that number as a result. The pair factors of 900 would be the two numbers which, when multiplied, give 900 as the result.

The following table represents the calculation of factors of 900 in pairs:

Factor Pair Pair Factorization
1 and 900 1 x 900 = 900
2 and 450 2 x 450 = 900
3 and 300 3 x 300 = 900
4 and 225 4 x 225 = 900
5 and 180 5 x 180 = 900
6 and 150 6 x 150 = 900
9 and 100 9 x 100 = 900
10 and 90 10 x 90 = 900
12 and 75 12 x 75 = 900
15 and 60 15 x 60 = 900
18 and 50 18 x 50 = 900
20 and 45 20 x 45 = 900
25 and 36 25 x 36 = 900
30 and 30 30 x 30 = 900

Since the product of two negative numbers gives a positive number, the product of the negative values of both the numbers in a pair factor will also give 900. They are called negative pair factors.

Hence, the negative pairs of 900 would be ( -1 , -900 ) , ( -2 , -450 ) , ( -3 , -300 ) , ( -4 , -225 ) , ( -5 , -180 ) , ( -6 , -150 ) , ( -9 , -100 ) , ( -10 , -90 ) , ( -12 , -75 ) , ( -15 , -60 ) , ( -18 , -50 ) , ( -20 , -45 ) , ( -25 , -36 ) and ( -30 , -30 ) .

What are factors?

In mathematics, a factor is that number which divides into another number exactly, without leaving a remainder. A factor of a number can be positive or negative.

Properties of factors

  • Each number is a factor of itself. Eg. 900 is a factor of itself.
  • 1 is a factor of every number. Eg. 1 is a factor of 900.
  • Every number is a factor of zero (0), since 900 x 0 = 0.
  • Every number other than 1 has at least two factors, namely the number itself and 1.
  • Every factor of a number is an exact divisor of that number, example 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 25, 30, 36, 45, 50, 60, 75, 90, 100, 150, 180, 225, 300, 450, 900 are exact divisors of 900.
