Did you know that 288 = 1+4+27+256 = 11 + 22 + 33 + 44 ? Like all even numbers (except for 2), 288 has more than one factor. However, it is one of those rare numbers, for which the exponents in its prime factorization are 5 and 2. In this lesson, we will calculate the factors of 288, prime factors of 288, and factors of 288 in pairs along with solved examples for a better understanding.
The numbers that divide 288 completely, without a remainder, are its factors. In other words, the factors of 288 are the numbers that get multiplied in pairs to create it. Look at the rainbow below to find which two numbers create 288 on multiplication. We factor those numbers repeatedly to get all the factors of 288. Explore factors using illustrations and interactive examples:
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.
All the divisors that we have got here, completely divide 288 without any remainder. Thus, all these divisors become the factors of 288. "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.
288 = 2 × 2 × 2 × 2 × 2 × 3 × 3= 25. × 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
The pair of numbers which gives 288 when multiplied are known as factor pairs of 288. Following are the factors of 288 in pairs.
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 go to slidego to slidego to slide
