Sometimes the hidden common factor is even harder to find. Consider the mapping {{vector|{{map|6 5 -4}} {{map|4 -4 1}}}}. To find this common factor, we need to linearly combine two of the first row {{map|6 5 -4}} and negative three of the 2nd row {{map|4 -4 1}} to produce {{map|0 22 -11}}. So we can see here that its common factor is 11. | Sometimes the hidden common factor is even harder to find. Consider the mapping {{vector|{{map|6 5 -4}} {{map|4 -4 1}}}}.

So we can see here that its common factor is 11. But there's no clear relationship between the numbers 2 and 3 and the number 11. And so we can begin to see that the problem of identifying enfactored mapping may not be very simple or straightforward. | ||
