Prime factorization method of finding the cube root of a number is the method in which the given number is resolved into its prime factors. Cube root of the numbers ending with 1, 8, 7, 4, 5, 6, 3, 2, 9 and 0 may have 1, 2, 3, 4, 5, 6, 7, 8, 9 and 0 respectively in their unit’s place. 1. So, the cube root of 74088 is found to be 2 x 3 x 7 = 42. The prime factorization can be summarised as shown in the figure below. Cube of root represented using the symbol ∛. Cube root of any number can also be represented in the form of an exponent as the number to the power ⅓. Cube of root represented using the symbol ∛. clashermalik clashermalik 14.11.2018 Math Secondary School Find the cube root of 46656 by prime factorization method 2 See answers sangharsh99 sangharsh99 Prime factors of 46656 is 2*2*2*2*2*2*3*3*3*3*3*3" cube root 2*2*3*3= 36 … Pro Lite, Vedantu Example: ∛8 = ∛(2 × 2 × 2) = 2.Since, 8 is a perfect cube number, it is easy to find the cube root of a number.. Finding the cubic root of non-perfect cube number is a little complex process but can be mastered easily. Let us try finding out the cube root of 74088. 3 27. What are the Uses of Prime Factorization Method in the Context of Cubes and Cube Roots? Sorry!, This page is not available for now to bookmark. To determine the cube root, one factor from each group is collected and multiplied together. How to Find Cube Root of 512. Cube root of a number can be found either by estimation method or by prime factorization method. 3 729 . If any number is left out without forming a group of three, zeros are appended to its left to make it a group of 3 digits. 46656 = 2 x 2 x 2 x 2 x 2 x 2 x 3 x 3 x 3 x 3 x 3 x 3. Pro Lite, Vedantu Now, consider the second group from the right. Since the number in the rightmost group ends with 1, the unit’s place of its cube root is 1. If not, this method can be used to find the least number to be multiplied or divided by the given number to make it a perfect cube. If the number is ‘p’, then its cube is p x p x p or p. . So, the cube root of a cube of the number is the number itself. The identical factors are then grouped. Cube and cube root are the most important concepts in various mathematical calculations. The cube root of a number ‘x’ is denoted as ∛x or (x)⅓ .
