To make 9, you can multiply 3 by 3 since 3 is a Prime number. To make 10, you can multiply 2 by 5, both of which are prime numbers. Finally, to make 12, you can multiply 2 by 2 by 3, as 2 and 3 are prime numbers. By multiplying these prime numbers together, you can obtain the desired results of 9, 10, and 12.
