Prime factorization of 24 is as following.
Without Exponents: 24 = 2 × 2 × 2 × 3
With Exponents:24 = 23 × 3
Upside-down division is a method used to find the prime factors and prime factorization of a number.
In this method, we draw a rectangular line and write the number on the RHS. Then we try to find a prime number that divides the number on the right. Once we find such a prime number, we write it on the left. We make the division and write the result under the number. on the RHS and continue the algorithm until we reach 1 on the RHS.
The numbers on the LHS are the prime factors. The prime factorization can be found by multiplying those prime numbers.
Upside-down division calculator,
