Best Answer

You need to carry out the division. If the remainder is 0 then it is divisible, if not it is not.

There are divisibility rules which can help with small or simple divisors but these are quite limited.

How do you know if the number is divisible by 6?

The Answer :)If the number is divisible by 2andIf the number is divisible by 3To find out if the number is divisible by 2 you look at the last digit of the number and see if it's an even number...ex: 420 you look at the 0 and 0 is a even number so 420 is divisible by 2.To find out if a number is divisible by 3 you add all the digits together and then see if the sum is divisible by 3...ex: 420 you add 4+2+0= 6 . and 6 is divisible by 3 so the number 420 is divisible by 3.yeah!

How do you know what numbers between 25-50 are prime?

To know what numbers are prime between 25-50, you'd have to figure out if any number besides 1 and that number itself can go into that number. Another key, is that all even numbers between 25 and 50 are NOT prime numbers. The only even number, that is prime is 2. So you'd have to go through all the odds between 25-50. For example: 27 is divisible by: 1,3,9, and 27 ~composite~ 29 is divisible by 1 and 29 ~prime~ Hope that helps!
