Question

Find the lcm of the numbers using list of multiples for numbers 14 21

Help me I don't understand

Answer 1

Find the lowest common multiple by stating out the multiples of 14 and 21. Like this:
14,28,42,56,70,84,98,112,126...
21,42,63,84...
There you have it. 84 is the lowest common multiple.
I HOPE THIS HELPS :) IM SORRY IF IM WRONG

Answer 2

the easiest way is to make a double bubble map if you know what those are. Start by putting 14 and 21 over each of the bubbles than find the multiples. Find the smallest ones that match and thats your answer. Hoped it helped
