Finding LCD

[ellymane]

What is the fastest way to find the least common denominator? For example, is there a faster way to find the LCD to this problem --> 5/16 + 2/5 + 1/6

I usually just multiply the denomonators together and reduce, but there is another way.

This uses the facors of all the numbers and multiplying them. Ask if you don't understand.

"faster" than what? How would YOU find the LCD.....if you show us your method, we could tell if there is something "faster" that you could use.
