Enter a number:

Prime Status: -- Divisible By:

A prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself.

Divisibility Tests:

2: Ends in 0, 2, 4, 6, or 8
3: Sum of digits divisible by 3
5: Ends in 0 or 5
9: Sum of digits divisible by 9
10: Ends in 0

This tool checks whether the input number is prime and whether it's divisible by common small numbers.
