Numbers: Integers
Factorization
The number #12# can be written as the product #\blue{3\times 4}#. We call #\blue{3\times 4}# a #\blue{\textbf{factorization}}# of #12#, since we factorized #12# into two factors that are both smaller than #12#. The product #\red{12\times 1}# is #\red{\textbf{not}}# a factorization of #12#, because the factor #12# is not smaller than #12#. In this case, we did not factorize #12#. Not every number can be factorized. For example, it does not work with the number #7#. If we write a positive integer as a product of smaller positive integers, |
Examples \[\begin{array}{rcl} |
Because #72# can be written as #2 \times 36# (among other options), #72# can be factorized.
