Cubes and Cube Roots
- A number is said to be a perfect cube if each of its prime factors appears in group of three.
- Prime factorization method can be used to check whether a number is a perfect cube or not.
For example, 5832 = 2 × 2 × 2 × 3 × 3 × 3 × 3 × 3 × 3
Here, each of the prime factors occurs in groups of three. Hence, 5832 is a perfect cube.
- We can use the method of prime factorization to find the smallest number with which the given number must be multiplied with or divided by to obtain a perfect cube.
