Best Answer

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.

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

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.
