Factors
A factor of a number is an exact divisor of that number, meaning it divides the number without leaving any remainder.
Multiples
A multiple of a number is obtained by multiplying that number by any natural number like 1, 2, 3, and so on.

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