6 and 12 have a least common multiple of 12

That would depend entirely on the given number.
Two pairs of numbers with 105 as their least common multiple are (15, 105) and (21, 105). This means that both pairs of numbers are multiples of 105 and their only common multiple is 105. The least common multiple is the smallest number that both numbers can divide evenly into.
The least common factor of 5 and 12 is the smallest number which divides both of them and it is 1, as it is for all pairs of numbers.(It is also the highest common factor of 5 and 12, as 5 and 12 only have one common factor: 1.)The least, or lowest, common multiple of a pair of numbers is the smallest number which is a multiple of both of them, which for 5 and 12 is 60.

There are many common multiples of 120 and 149. A common multiple is simply a multiple of both numbers. The least common multiple is 120x149, since 149 is prime. (Note: this trick doesn't work on all pairs of number. Although the product is always a multiple, it's not the least common multiple.)
