18 years, 36 years, 54 years, 72 years, 90 years, 108 years, 126 years, 144 years... When we compare the multiples of eight and eighteen, we can see that the smallest one they have in common is 72. As a result, the LCM of 8 and 18 is 72. Anything multiplied by 72 is also multiplied by 8 and 18 combined. The LCM is the least number you can multiply by both 8 and 18 without changing the value of the product.

There are two ways to find the LCM of numbers: the fast way and the slow way. Which method you use depends on how many numbers you are working with. It's easy to calculate the LCM of two numbers; just add up **all the numbers** you can divide by each number without changing the result. For example, if you want to know the LCM of 8 and 18, simply add 2 + 1 + 0 + 0 + 0 + 0 = 10. Now, let's say you have a list of five numbers to find the LCM of. You would do the same thing with each number in the list until you had used them all up. In **this case**, you would add up all the numbers you could divide by 5 without changing the result (2 + 1 + 0 + 0 + 0 = 4). Now, you can see that 4 times 10 was once again divided by 5 without changing the result. Therefore, the LCM of 8 and 18 is 4096.

## What is the lowest common factor between 48 and 18?

In all, the lcm of 48 and 18 is 144. Lcm (48,18) Equals 144 in **ordinary notation**.

The GCF of 18 and 48 is the greatest integer that divides 18 and 48 perfectly without leaving **any residue**. The factors of 18 and 48 are respectively 1, 2, 3, 6, 9, 18 and 1, 2, 3, 4, 6, 8, 12, 16, 24, and 48.

## What is the highest multiple of 16?

16, 32, 48, 64, 80, 96, 112, 128, 144, 160,... are all multiples of 16. As a result, the frequent multiples of 12 and 16 are 48, 96, 144,..., and the LCM is 48. The numbers that are multiples of 24 are 0, 24, 48,... As a result, the LCM of 12, 16, and 24 is 48. 12 and 15 have an LCM of 60. 99 has an LCM of 20, 100 has an LCM of 20.

12, 16, 24, 30, 36, 42, 48, 54, 60, 66, 72, 78, 84, 90, 96, 102, 108, 114, 120, 126, 132, 138, 144, 150, 156, 162, 168, 174, 180.. Are all multiples of 12.

## What is the lowest common denominator between 8 and 12?

24 is the smallest common multiple of 8 and 12.

12 is the least possible value of x that yields a result that is equal to 8.

8 is the least possible value of x that yields a result that is equal to 24.

The calculator gives us 8 as the answer but I don't think it's right. Am I missing something here?

Here's how I calculated it:

8*12 = 96; 95 is not equal to 24 so this method doesn't work.

I hope you can help me with this problem because I'm stuck on it.

Thanks in advance!
