i think it’s 2…?

Help me with: Pregnancy & Sleepiness

that’s the greatest common factor.

240, I think.

OK - you can have one freebie. It’s 120. Here’re the directions so you can do the rest of the problems:

To use this method factor each of the numbers into primes. Then for each different prime number in all of the factorizations, do the following…

Count the number of times each prime number appears in each of the factorizations.

For each prime number, take the largest of these counts.

Write down that prime number as many times as you counted for it in step 2.

The least common multiple is the product of all the prime numbers written down.

Example: Find the least common multiple of 5, 6 and 15.

Factor into primes

Prime factorization of 5 is 5

Prime factorization of 6 is 2 x 3

Prime factorization of 15 is 3 x 5

Notice that the different primes are 2, 3 and 5.

Now, we do Step #1 - Count the number of times each prime number appears in each of the factorizations…

The count of primes in 5 is one 5

The count of primes in 6 is one 2 and one 3

The count of primes in 15 is one 3 and one 5

Step #2 - For each prime number, take the largest of these counts. So we have…

The largest count of 2s is one

The largest count of 3s is one

The largest count of 5s is one

Step #3 - Since we now know the count of each prime number, you simply - write down that prime number as many times as you counted for it in step 2.

Here they are…

2, 3, 5

Step #4 - The least common multiple is the product of all the prime numbers written down.

2 x 3 x 5 = 30

Therefore, the least common multiple of 5, 6 and 15 is 30.

So there you have it. A quick and easy method for finding least common multiples.
