For example:
LCM(3, 5) = 15
but 3 × 5 ÷ 2 = 7½
LCM(4, 8) = 8
but 4 × 8 ÷ 2 = 16
Multiplying two numbers and dividing by 2 will ONLY work when the Highest Common Factor of the two numbers is 2.
For any two numbers: LCM = product ÷ HCF

Is it true you can always find a common multiple of a pair of numbers by multiplying them together?
No you can't, but sometimes you can.
Can you always find the least common multiple of two numbers by multiplying them together.why or why not?
You can always find a common multiple of two numbers by multiplying them together; it will not always be the least common multiple. As one counterexample, if one of the numbers is a multiple of the other, the first number is the LCM of the two. 9 x 3 = 27 The LCM of 9 and 3 is 9. 4 x 6 = 24 The LCM of 4 and 6 is 12.

Yes, by multiplying them together.
Can you always find the least common multiple of 2 numbers by multiplying them together?
No, that will not always work. in the case for some numbers it will work. for example 3 * 4 = 12. it works here. however if you do that for 30 and 20, you will get 600. the real lowest common multiple is 60. so it does not always work.
