Question

Find two numbers that have 2, 3, and 5 as factors. What other factors do those two numbers have in common?

Answer 1

To find the first number, just multiply the three numbers together.
$2*3*5 \\ 6*5 \\ 30$

To find the second number, multiply the three numbers together along with another number (this number can be anything).
$2*3*5*4 \\ 6*5*4 \\ 30*4 \\ 120$

What They Have in Common:
- All numbers will be even, since you are multiplying by 2.
- All numbers will end in a zero, since you are multiplying by 5 and also 2.
