ACT Math: Pre-Algebra Drill 5, Problem 2. If a and b are prime numbers, how many factors does ab have?
|Foreign Language||Arabic Subtitled|
Multiples, factors of integers, and primes
|Product Type||ACT Math|
So like... let's say a is 2 and b is 3... both prime numbers.
a times b is 6, which has 4 factors: 1 and 6, but also 2 and 3.
So there are... 4.
We could try the same with a few other pairs of prime numbers, but we're always going
to arrive at the same answer.
Which is what makes math so lovely.
