Is any number divisible by any number?
Every number is divisible by 1 If a number ends in 0, 2, 4, 6, or 8 (even), the number is divisible by 2. If the sum of a number’s digits is a multiple of 3, the number is divisible by 3. For example, 324 is divisible by 4 because 4 divides 24, and 1500 is divisible by 4 because the last two digits are 0’s.
Is N divisible by 2?
We know that any integer is in the form of 2q or 2q+1, where q is some integer. Therefore, from statement 1 and 2 we can conclude that ${n^2} + n$ is divisible by 2 for any positive integer n.
Is 431 divisible by any number?
