How do you find the LCM of 20/30?

Dec 8, 2016

The answer is $60$.

Explanation:

To solve this, I used my head, but if you were to use extremely high numbers, what you could try is multiplying the two numbers together.

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

$\frac{600}{10} = 60$
