Frequently Asked Questions
Is 1 a prime number?
No, 1 is neither prime nor composite because it has only one factor (itself).
How can I easily check if a large number is divisible by 3?
Add all the digits of the number. If the sum is divisible by 3, then the entire number is divisible by 3.
What is the difference between a factor and a multiple?
A factor is always less than or equal to the number and divides it completely. A multiple is greater than or equal to the number and is obtained by multiplying it by counting numbers.
