Question

Find the LCM of 7 and 12. Show your work.

Answer 1

This is what I have SO far but I know the answers 84

Answer 2

So... since you already know the answer is 84, which is correct.

7 is a prime number.
\[7^{1}\]12, however is not.
\[2*2*3 => 2^2 * 3^1\]The new list of numbers (from 7,12) is...
2,2,3,7

Multiply these to get the LCM

\[LCM = 2 * 2 * 3 * 7 = 84\]Exponential form;
\[LCM = 2^2 * 3^1 * 7^1 = 84\]LCM = 84

Therefore, LCM(7,12) = 84
