How do you find the Least common multiple of 15, 20?

Answer 1

LCM = 60

Let's first find the prime factors of these two numbers:

#15=3xx5# #20=2xx2xx5#

The LCM will have all the prime factors from the two numbers but we can drop replicates across the numbers we're doing this for. In this example:

From 15, we get both the 3 and the 5

From 20, we get two 2s - the 5 is already accounted for in the 5 from the 15.

The LCM is:

#2xx2xx3xx5=4xx15=60#
#15xx2xx2=60# #20xx3=60#

Answer 2

To find the least common multiple (LCM) of 15 and 20, you first factor each number into its prime factors. Then, you take the highest power of each prime factor that appears in the factorization of either number, and multiply them together.

15 = 3 × 5 20 = 2^2 × 5

The LCM is the product of the highest power of each prime factor: LCM(15, 20) = 2^2 × 3 × 5 = 60

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.
