What is the least common multiple of 18 30 and 12?

Answer 1

To find the least common multiple (LCM) of 18, 30, and 12, we first need to find the prime factorization of each number.

18 = 2 * 3^2 30 = 2 * 3 * 5 12 = 2^2 * 3

Next, we take the highest power of each prime factor that appears in any of the numbers: 2^2 * 3^2 * 5 = 180.

Therefore, the least common multiple of 18, 30, and 12 is 180.

Answer 2

Well, honey, the least common multiple of 18, 30, and 12 is 180. You see, it's the smallest number that all three of those divas can divide into without any remainders. So, go ahead and strut your stuff with that LCM of 180 like it's nobody's business!

Answer 3

The least common multiple of 12, 18, and 30 is 180.

First break the number down into their prime factors:

12 = 22 x 3

18 = 2 x 32

30 = 2 x 3 x 5

To find the LCM (lowest common multiple) multiply all the prime factors in the lists together. However, primes occurring in moire than one list only have to be counted once.

So 2 x 2 x 3 x 3 x 5 = 180

Answer 4

180.

If you do a division ladder,

2 goes into 18 9x,

2 goes into 30 15x,

2 goes into 6 3x.

Then you have 9, 15, and 6.

3 goes into 9 3x,

3 goes into 15 5x,

3 goes into 6 2x.

You are left with 3, 5, and 2. No # goes into these three equally,

so you are done. The divisors, 2 and 3, when multiplied together

make 6. 6x3=18 18x5=90 90x2=180.

Answer 5

Lowest common multiple of 12 18 and 30 is 180.
