How do you find the LCM of 20/30?

Answer 1

The answer is #60#.

I used my head to solve this, but you could try multiplying the two numbers together if you were using really high numbers.

For this case, that is #600#. Then, you find the GCF of the two numbers. In this case, that would be #10#. You take the product and divide it by the GCF. This will yield

#600/10 = 60#

and you have your response.

To find the Least Common Multiple (LCM) of fractions, follow these steps:

Find the LCM of the denominators.
Multiply the LCM of the denominators by the highest common factor (HCF) of the numerators.

Given ( \frac{20}{30} ):

The LCM of 20 and 30 is 60.
The HCF of 20 and 30 is 10.

So, ( \text{LCM}(20/30) = 60 \times 10 = 600 ).

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.
