Divisors VS Factors

Other responders have covered the main point: the words "divisor" and "factor" are completely interchangeable.

For example, the divisors of 12 are 1, 2, 3, 4, 6, and 12. The factors of 12 are... you guessed it. The exact same list.

Thus, you can make the observation that 1 is a factor/divisor of every number, and every number is a factor/divisor of itself.

Make sure not to confuse divisors with multiples! Multiples of 12 include 12, 24, 36, etc. That's right, every number is considered a multiple of itself.

Also, note the following list of facts:

The factors of 12 are 1, 2, 3, 4, 6, and 12.
The prime factorization of 12 is 12= 2*2*3.
12 has 6 factors (listed above).
The unique prime factors of 12 are only 2 and 3.

Hope this helps keep all of those things distinct!
