Given numbers are 478,668,819,990

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

The LCM of 478,668,819,990 is 7191524340.

Find LCM of 478,668,819,990 with Prime Factorization

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

2 x 3 x 3 x 239 x 334 x 91 x 55 = 7191524340

Therefore, the lowest common multiple of 478,668,819,990 is 7191524340.

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.

478 x 668 x 819 x 990 = 258894876240

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.

478 : 1, 2, 239, 478

668 : 1, 2, 4, 167, 334, 668

819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 478,668,819,990, is 1.

Now, the common factors can be found like this.

478:2x 239

668:2x 2x 167

819:3x 3x 7x 13

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 3 = 36

Therefore, the value for common factors is 36.

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 = 258894876240/(1x36)

LCM = 258894876240/36

LCM = 7191524340

Thus, we can understand that the LCM of 478,668,819,990 is 7191524340.
