Given numbers are 334,405,391,816

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

The LCM of 334,405,391,816 is 423124560.

Find LCM of 334,405,391,816 with Prime Factorization

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

2 x 3 x 17 x 167 x 135 x 23 x 8 = 423124560

Therefore, the lowest common multiple of 334,405,391,816 is 423124560.

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.

334 x 405 x 391 x 816 = 43158705120

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.

334 : 1, 2, 167, 334

405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405

391 : 1, 17, 23, 391

816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 334,405,391,816, is 1.

Now, the common factors can be found like this.

334:2x 167

405:3x 3x 3x 3x 5

391:17x 23

816:2x 2x 2x 2x 3x 17

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 17 = 102

Therefore, the value for common factors is 102.

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 = 43158705120/(1x102)

LCM = 43158705120/102

LCM = 423124560

Thus, we can understand that the LCM of 334,405,391,816 is 423124560.
