OK, a least common denominator is composed of prime numbers. As has been proven by mathematicians thousands of years ago, there is an infinite amount of prime numbers.
Let's begin with the first five; 2, 3, 5, 7, 11
Let's let 2 = You missed your 8th grade graduation because you had jury duty.
Let's let 3 = You invite your 14 year old daughter over for dinner along with all of her kids
Let's let 5 = You think the Waffle House is an upscale restaurant
Let's let 7 = You can burp and say your name at the same time
Let's let 11 = Your pickup truck has chrome bull balls hanging off the trailer hitch
If you check the box to two or more of the five above, you will find yourself in the least common denominator category.
If needed, we can expand the sampling size of the aforementioned population to increase the desired confidence level.
silentbuddha, I hope this is serious enough. We're dealing with mathematics and statistics.
