Given numbers are 399,330,348,990

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

The LCM of 399,330,348,990 is 7636860.

Find LCM of 399,330,348,990 with Prime Factorization

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

2 x 3 x 5 x 11 x 133 x 1 x 58 x 3 = 7636860

Therefore, the lowest common multiple of 399,330,348,990 is 7636860.

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.

399 x 330 x 348 x 990 = 45362948400

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.

399 : 1, 3, 7, 19, 21, 57, 133, 399

330 : 1, 2, 3, 5, 6, 10, 11, 15, 22, 30, 33, 55, 66, 110, 165, 330

348 : 1, 2, 3, 4, 6, 12, 29, 58, 87, 116, 174, 348

990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 399,330,348,990, is 3.

Now, the common factors can be found like this.

399:3x 7x 19

330:2x 3x 5x 11

348:2x 2x 3x 29

990:2x 3x 3x 5x 11

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 3x 3x 5x 11 = 1980

Therefore, the value for common factors is 1980.

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 = 45362948400/(3x1980)

LCM = 45362948400/5940

LCM = 7636860

Thus, we can understand that the LCM of 399,330,348,990 is 7636860.
