Question 33068This question is from textbook Saxon Algebra 1

: I don't understand how to figure out least common multiples when there are exponents involved?
ex. 4c^3, c^2, and 3c^4
OK, so it's 4*c*c*c, c*c, and 3*c*c*c*c.....
so, 4*3*c*c*c*c
The answer is 12c^4, but WHY do we use the greatest exponent....c^3 doesn't go into c^4.....??????
