Given numbers are 643,706,298,305

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

The LCM of 643,706,298,305 is 20630121310.

Find LCM of 643,706,298,305 with Prime Factorization

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

2 x 643 x 353 x 149 x 305 = 20630121310

Therefore, the lowest common multiple of 643,706,298,305 is 20630121310.

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 706 x 298 x 305 = 41260242620

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

706 : 1, 2, 353, 706

298 : 1, 2, 149, 298

305 : 1, 5, 61, 305

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 643,706,298,305, is 1.

Now, the common factors can be found like this.

643:643

706:2x 353

298:2x 149

305:5x 61

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

2 = 2

Therefore, the value for common factors is 2.

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 = 41260242620/(1x2)

LCM = 41260242620/2

LCM = 20630121310

Thus, we can understand that the LCM of 643,706,298,305 is 20630121310.
