324
You can multiply 2 and 9 to get 18. Alternatively, you can multiply 3 and 6 to get 18 as well.
Multiply 4 to 18, and 3 to 24. You get a denominator of 72
3x6
The two numbers that add up to -36 and multiply to 324 are -18 and -18. This is because -18 + -18 equals -36, and -18 * -18 equals 324.
Presumably, the theory is that it's easier to multiply by small numbers than larger ones. If there's a number that you need multiplied by 18, multiply it by 3, then multiply that total by 3, then multiply that total by 2.

If you meant what whole numbers can you use to multiply to 18, there's 9x2, 6x3, and of course 1x18 but you could multiply any number[s] to 18
you multiply 27 times a number then you multiply 18 times a different number and see if they come out with the same answer.

18
Multiply 18 by successive counting numbers.
The two numbers that add up to -36 and multiply to 324 are -18 and -18. This is because -18 + -18 equals -36, and -18 * -18 equals 324.
Multiply 11 by 18 and multiply that total by 2 and 3.
Presumably, the theory is that it's easier to multiply by small numbers than larger ones. If there's a number that you need multiplied by 18, multiply it by 3, then multiply that total by 3, then multiply that total by 2.
