The numbers are the same as positive numbers, just the signs change. Write out the factor pairs as if the number were positive, but make one of the numbers positive and one negative. Now write the same pairs over again and reverse the signs. Negative numbers have twice as many factor pairs as positive numbers do.
The smallest positive factor of any positive integer is the number 1. If negative factors are allowed, the smallest factor is the negative of the absolute value of any integer.
The same as with positive numbers. The factors of negative numbers have the same absolute value. One set positive, one set negative. Example: -12 1,2,3,4,6,12,-1,-2,-3,-4,-6,-12
