Given numbers are 284,415,345,921,440

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

The LCM of 284,415,345,921,440 is 54925824360.

Find LCM of 284,415,345,921,440 with Prime Factorization

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

2 x 2 x 3 x 5 x 71 x 83 x 23 x 307 x 22 = 54925824360

Therefore, the lowest common multiple of 284,415,345,921,440 is 54925824360.

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.

284 x 415 x 345 x 921 x 440 = 16477747308000

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.

284 : 1, 2, 4, 71, 142, 284

415 : 1, 5, 83, 415

345 : 1, 3, 5, 15, 23, 69, 115, 345

921 : 1, 3, 307, 921

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 284,415,345,921,440, is 1.

Now, the common factors can be found like this.

284:2x 2x 71

415:5x 83

345:3x 5x 23

921:3x 307

440:2x 2x 2x 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 5x 5 = 300

Therefore, the value for common factors is 300.

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 = 16477747308000/(1x300)

LCM = 16477747308000/300

LCM = 54925824360

Thus, we can understand that the LCM of 284,415,345,921,440 is 54925824360.
