Given numbers are 457,860,445,320

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

The LCM of 457,860,445,320 is 559660480.

Find LCM of 457,860,445,320 with Prime Factorization

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

2 x 2 x 5 x 457 x 43 x 89 x 16 = 559660480

Therefore, the lowest common multiple of 457,860,445,320 is 559660480.

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.

457 x 860 x 445 x 320 = 55966048000

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.

457 : 1, 457

860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860

445 : 1, 5, 89, 445

320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 457,860,445,320, is 1.

Now, the common factors can be found like this.

457:457

860:2x 2x 5x 43

445:5x 89

320:2x 2x 2x 2x 2x 2x 5

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 5x 5 = 100

Therefore, the value for common factors is 100.

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 = 55966048000/(1x100)

LCM = 55966048000/100

LCM = 559660480

Thus, we can understand that the LCM of 457,860,445,320 is 559660480.
