Question

what will be the LCM of x-2 x-4

​

Answer 1

Step-by-step explanation:

Since x^4 is a multiple of x^2, x^4 will be the lowest common multiple of these two and x^15 is x^11 * x^4, so the LCM of x^2, x^4 and x^15 is x^15, since

x^2 * x^13 = x^15.

x^4 * x^11 = x^15 and

x^15 * 1 = x^15

If the question was asking for a Lowest Common Factor of all 3, then this would have been a much more fun question to answer.
