Given numbers are 643,813,698,349

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

The LCM of 643,813,698,349 is 364885782.

Find LCM of 643,813,698,349 with Prime Factorization

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

349 x 643 x 813 x 2 x 1 = 364885782

Therefore, the lowest common multiple of 643,813,698,349 is 364885782.

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.

643 x 813 x 698 x 349 = 127345137918

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.

643 : 1, 643

813 : 1, 3, 271, 813

698 : 1, 2, 349, 698

349 : 1, 349

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 643,813,698,349, is 1.

Now, the common factors can be found like this.

643:643

813:3x 271

698:2x 349

349:349

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

349 = 349

Therefore, the value for common factors is 349.

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 = 127345137918/(1x349)

LCM = 127345137918/349

LCM = 364885782

Thus, we can understand that the LCM of 643,813,698,349 is 364885782.
