Given numbers are 390,317,395,725,840

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

The LCM of 390,317,395,725,840 is 39653086200.

Find LCM of 390,317,395,725,840 with Prime Factorization

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

2 x 3 x 5 x 13 x 317 x 79 x 145 x 28 = 39653086200

Therefore, the lowest common multiple of 390,317,395,725,840 is 39653086200.

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.

390 x 317 x 395 x 725 x 840 = 29739814650000

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.

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

317 : 1, 317

395 : 1, 5, 79, 395

725 : 1, 5, 25, 29, 145, 725

840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 390,317,395,725,840, is 1.

Now, the common factors can be found like this.

390:2x 3x 5x 13

317:317

395:5x 79

725:5x 5x 29

840:2x 2x 2x 3x 5x 7

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

2x 3x 5x 5x 5 = 750

Therefore, the value for common factors is 750.

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 = 29739814650000/(1x750)

LCM = 29739814650000/750

LCM = 39653086200

Thus, we can understand that the LCM of 390,317,395,725,840 is 39653086200.
