Given numbers are 643,498,329,166

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

The LCM of 643,498,329,166 is 105350406.

Find LCM of 643,498,329,166 with Prime Factorization

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

2 x 83 x 643 x 3 x 329 x 1 = 105350406

Therefore, the lowest common multiple of 643,498,329,166 is 105350406.

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 498 x 329 x 166 = 17488167396

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

498 : 1, 2, 3, 6, 83, 166, 249, 498

329 : 1, 7, 47, 329

166 : 1, 2, 83, 166

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 643,498,329,166, is 1.

Now, the common factors can be found like this.

643:643

498:2x 3x 83

329:7x 47

166:2x 83

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

2x 83 = 166

Therefore, the value for common factors is 166.

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 = 17488167396/(1x166)

LCM = 17488167396/166

LCM = 105350406

Thus, we can understand that the LCM of 643,498,329,166 is 105350406.
