How To Calculate Factors of 288

We know that 288 is a composite number and must be having many factors. Using the divisibility rules, we find the factors of 288 starting from 1.

288 ÷ 1=288
Check if 288 is divisible by 2, as it is an even number.
288 ÷ 2 =144
288 ÷ 3 = 96
288 ÷ 4 =72
288 is not divisible by 5
288 ÷ 6 = 48
288 is not divisible by 7
288 ÷ 8 = 36
288 ÷ 9 = 32
288 is not divisible by 10 and 11
288 ÷ 12 = 24
288 is not divisible by 13, 14 and 15
288 ÷ 16 = 18

All the divisors that we have got here, completely divide 288 without any remainder. Thus, all these divisors become the factors of 288.

Factors of 288 by Prime Factorization

"Prime factorization is to express a composite number as the product of its prime factors." To find the prime factors of a composite number, keep dividing it by the prime numbers one by one, until there are no composite factors left. The prime factorization of 288 is shown below by the ladder method.

prime factorization of 288

288 is a composite number. We know that 288 is divisible by 2. 144 ÷ 2. Thus, we break it further into 2 factors. 72 ÷ 2
72 can be factored as 36 ÷ 2
36 is factored as 18 ÷ 2
18 is factored as 9 ÷ 2
9 is factored as 3 ÷ 3
Since we have no more composite number, we can stop here. Below is the factor tree of 288.

prime factors of 288- factor tree

288 = 2 × 2 × 2 × 2 × 2 × 3 × 3= 2^5.× 3². The prime factors of 288 are 2 and 3. Now that we have done the prime factorization of our number, we can multiply them and get all the other possible factors.

Tips and Tricks

Use the ladder method or factor tree to find the prime factorization of a composite number.
Do the prime factorization of the number, multiply them and get all the possible composite factors.
288 = 2 × 2 × 2 × 2 × 2 × 3 × 3= 2⁵× 3². To determine the number of factors of 288, add one to each of these exponents and multiply them. (5+1) (2+1) = 6 × 3 = 18
Use the rainbow method to find the factor-pairs.

16 × 18	-16 × -18

Important Notes

288 is a composite number with 18 factors.
The factors of a number divide it completely without any remainder. 288 ÷ 3 =96, with remainder = 0
The factors of 288 that add up to 6 = 1 + 2 + 3 . Factors of 288 that add up to 42 are 18 + 24

Example 1: Jane is given a few number cards numbered from 10 to 15, She is asked to find the factors of 288 between 10 and 15, Can you help her?

Solution:

To know if a number is a factor, we will check all the numbers between 10 and 15 to know which numbers completely divide 288 without leaving any remainder.

288 ÷ 10 = 28, Remainder = 8

288 ÷11 = 26, Remainder = 2

288 ÷ 12 = 24, Remainder = 0

288 ÷ 13 = 22, Remainder = 2

288 ÷ 14 = 20, Remainder = 8

288 ÷ 15 = 19, Remainder = 3

This shows that only 12 is a factor of 288.
Example 2: Paul has 288 cookies. He needs to put 9 cookies in each box. How many boxes will he use?

Solution:

9 cookies × number of boxes = 288 cookies

9 × _____= 288
He needs to find the missing factor.
9 × 32 = 288
Therefore, he will use 32 boxes.
Example 3: Mia builds a rectangular base mat with 288 unit blocks. She has built a row of 16 blocks. How many such rows of blocks does she need to arrange to get the full rectangular base?

Solution:

16 blocks × number of rows = 288 blocks

16 × ______= 288
Finding the missing factor, we get 16 × 18 = 288
Thus she needs 18 more such rows of 16 to complete the rectangle.
