What is the unit's digits of the product of the first 21 prime numbers?
Oh, dude, you want to know the unit's digits of the product of the first 21 prime numbers? Well, let me casually tell you that the unit's digit of a product depends on the unit's digits of the numbers being multiplied. Since the unit's digit of all prime numbers greater than 5 is either 1, 3, 7, or 9, the product of the first 21 prime numbers will end in a unit's digit that is a result of multiplying these digits together. Cool, right?

First you add up all of the digit's, and then divide. If 6 fits in it, then 3 also fits in it, but not 9. (For ex. Is 6 a factor of 674. 6+7+4=17, 17/6=2.8. so no, 6 is not a factor of 674) If your number is even and divisible by three, it's divisible by 6.
