Given numbers are 440,286,671,388,260

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

The LCM of 440,286,671,388,260 is 33845240.

Find LCM of 440,286,671,388,260 with Prime Factorization

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

2 x 2 x 5 x 11 x 13 x 2 x 1 x 61 x 97 x 1 = 33845240

Therefore, the lowest common multiple of 440,286,671,388,260 is 33845240.

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.

440 x 286 x 671 x 388 x 260 = 8518170003200

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.

440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440

286 : 1, 2, 11, 13, 22, 26, 143, 286

671 : 1, 11, 61, 671

388 : 1, 2, 4, 97, 194, 388

260 : 1, 2, 4, 5, 10, 13, 20, 26, 52, 65, 130, 260

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 440,286,671,388,260, is 1.

Now, the common factors can be found like this.

440:2x 2x 2x 5x 11

286:2x 11x 13

671:11x 61

388:2x 2x 97

260:2x 2x 5x 13

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 2x 2x 2x 5x 11x 11x 13 = 251680

Therefore, the value for common factors is 251680.

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 = 8518170003200/(1x251680)

LCM = 8518170003200/251680

LCM = 33845240

Thus, we can understand that the LCM of 440,286,671,388,260 is 33845240.
