How do I get the common multiple of 12, 20, and 35? I am not sure I understand the process.

I have 18 toy vans I give7 to lexiev. and 2 to kaitlynne how many do I stil have

The common multiple is the number that can be divided evenly by all three numbers. Hint: try 12 x 35. Is that answer divisible by 20?

To find the common multiple of 12, 20, and 35, you can start by finding the prime factors of each number.

12 = 2^2 * 3
20 = 2^2 * 5
35 = 5 * 7

Then, you can find the least common multiple (LCM) by taking the highest power of each prime factor that appears in any of the numbers. So the LCM would be:

2^2 * 3 * 5 * 7 = 420

Therefore, the common multiple of 12, 20, and 35 is 420.

For the second question, if you have 18 toy vans and you give 7 to Lexiev, and 2 to Kaitlynne, you need to subtract the total number of vans given away from the original number of vans to find out how many you still have.

18 - 7 - 2 = 9

So you still have 9 toy vans.
