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.
