Attacker- when you get to dividing decimals and decimal problems, I'll give you the links to 2 videos that help.

If you need help it would be beneficial if you look up your problematic topics in YouTube. For example, if you want to learn about Prime Factorization, just type Prime Factorization on YouTube's search bar and watch the videos. Hope it helps :)

so you would find the smallest number that goes into all of those numbers and that would be your lcm for your problem it would be 70 because it is the smallest number any of them go into. Another ex would be 1,2, and 3 your lcm would be6 because it is the smallest number that they all go into

Ok the LCM... lets use 5 and 10 as an example:
Multiples of 5: 5,10,15,20,25,30,35,40
Multiples of 10: 10,20,30,40
The first number that appears in both is 10 so the LCM would be 10. Edit: Apparently there is nothing called least common factor

Very easy its the group numbers that you multiply that are in common. Like the LCM of 8 and 6 is 24. 8 x 3=24 and 6 x 4=24 . also to remember list their multiples until you find the first one they both have.
