What is the LCM of 3, 5, 15, 16?

Answer 1

240

I prefer to prime factorize problems involving LCMs first:

#3=3# #5=5# #15=3xx5# #16=2xx2xx2xx2#

And all of the primes will now be listed in the LCM.

We can now move on to the 16 which has four 2s because we have a 3 from the 3 and a 5 from the 5. Since the 3 and 5 of the 15 are already listed, the LCM is:

#3xx5xx2xx2xx2xx2=15xx16=240#
#3 xx80=240# #5xx48=240# #15xx16=240#

Answer 2

To find the least common multiple (LCM) of 3, 5, 15, and 16, you can start by breaking down each number into its prime factors.

3 = 3 (prime) 5 = 5 (prime) 15 = 3 * 5 16 = 2^4

Then, you take the highest power of each prime factor that appears in any of the numbers:

2^4 * 3 * 5 = 240

So, the LCM of 3, 5, 15, and 16 is 240.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
