The first five common multiples are the first five multiples of the lowest common multiple. lcm(5, 6): 5 = 5 6 = 2 x 3 → lcm = 2 x 3 x 5 = 30 → first 5 common multiples of 5 and 6 are: 30 x 1 = 30 30 x 2 = 60 30 x 3 = 90 30 x 4 = 120 30 x 5 = 150
If there is a number in front of the first x then you multiply that number by the end number and then you have to find a number that multiplies to that and adds to the middle term's number. Ex. 3x(squared) + 5x -2=0 So in that example, you would multiply the 3 by the -2 and get -6. So then, ask yourself what multiplies to -6 and adds to 5 (the middle term). The answer to this example is +6 and -1 (6 * -1= -6 and 6+-1= 5) Then, you break down the middle term into those two terms.
6 and 1
30, 60, and 90.
30, 60 and 90

This may be the worst answer but here it goes: 24 is the least common multiple of 6 and 8.
The common multiplies of 6 and 8 that are under 80 are 24, 48, 72

-2 and -3 -2 + (-3) = -5 -2 x -3 = 6
