Factors and Multiples
A factor is a number that divides another number completely without leaving a remainder, while a multiple is the product of that number and any whole number.
Prime and Composite Numbers
Prime numbers have only two factors (1 and themselves), whereas composite numbers have more than two factors.

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 find the LCM of two large numbers?
You can use the prime factorization method or the division method to find the LCM quickly.
Why do we use divisibility rules?
Divisibility rules help us check whether a number can be divided by another number quickly without doing long division.
