Given numbers are 321,39,845

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

The LCM of 321,39,845 is 271245.

Find LCM of 321,39,845 with Prime Factorization

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

3 x 13 x 107 x 1 x 65 = 271245

Therefore, the lowest common multiple of 321,39,845 is 271245.

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.

321 x 39 x 845 = 10578555

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.

321 : 1, 3, 107, 321

39 : 1, 3, 13, 39

845 : 1, 5, 13, 65, 169, 845

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 321,39,845, is 1.

Now, the common factors can be found like this.

321:3x 107

39:3x 13

845:5x 13x 13

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

3x 13 = 39

Therefore, the value for common factors is 39.

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 = 10578555/(1x39)

LCM = 10578555/39

LCM = 271245

Thus, we can understand that the LCM of 321,39,845 is 271245.

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