Pairs of numbers whose sum is -14 and that are factors of -189 include -7 and -7, and -21 and 7.
When the "factors" of a number are listed, the list is usually restricted to positive factors. Then there would be no answer to the question, because no group of positive numbers can add up to make zero.
The two numbers that have 105 as their least common multiple (LCM) are 15 and 7. This is because the LCM of two numbers is the smallest number that is a multiple of both numbers. In this case, 15 and 7 are both factors of 105, and no smaller number can be a multiple of both 15 and 7.
Each of these factor pairs (multiply the numbers in parentheses) equals 441: (1, 441) (3, 147) (7, 63) (9, 49) (21, 21)
3 and 7, among others.
