Given numbers are 18,86,86,353

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 18,86,86,353 is 273222.

Find LCM of 18,86,86,353 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

2 x 43 x 9 x 1 x 1 x 353 = 273222

Therefore, the lowest common multiple of 18,86,86,353 is 273222.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

18 x 86 x 86 x 353 = 46994184

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

18 : 1, 2, 3, 6, 9, 18

86 : 1, 2, 43, 86

86 : 1, 2, 43, 86

353 : 1, 353

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 18,86,86,353, is 1.

Now, the common factors can be found like this.

18:2x 3x 3

86:2x 43

86:2x 43

353:353

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 2x 43 = 172

Therefore, the value for common factors is 172.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 46994184/(1x172)

LCM = 46994184/172

LCM = 273222

Thus, we can understand that the LCM of 18,86,86,353 is 273222.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 13, 59, 38, 561
• LCM of 91, 29, 97, 420
