Given numbers are 698,664,406,399

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

The LCM of 698,664,406,399 is 2681417256.

Find LCM of 698,664,406,399 with Prime Factorization

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

2 x 7 x 349 x 332 x 29 x 57 = 2681417256

Therefore, the lowest common multiple of 698,664,406,399 is 2681417256.

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.

698 x 664 x 406 x 399 = 75079683168

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.

698 : 1, 2, 349, 698

664 : 1, 2, 4, 8, 83, 166, 332, 664

406 : 1, 2, 7, 14, 29, 58, 203, 406

399 : 1, 3, 7, 19, 21, 57, 133, 399

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 698,664,406,399, is 1.

Now, the common factors can be found like this.

698:2x 349

664:2x 2x 2x 83

406:2x 7x 29

399:3x 7x 19

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 7 = 28

Therefore, the value for common factors is 28.

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 = 75079683168/(1x28)

LCM = 75079683168/28

LCM = 2681417256

Thus, we can understand that the LCM of 698,664,406,399 is 2681417256.
