Given numbers are 813,645,466,478

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

The LCM of 813,645,466,478 is 19467618330.

Find LCM of 813,645,466,478 with Prime Factorization

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

2 x 3 x 271 x 215 x 233 x 239 = 19467618330

Therefore, the lowest common multiple of 813,645,466,478 is 19467618330.

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.

813 x 645 x 466 x 478 = 116805709980

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.

813 : 1, 3, 271, 813

645 : 1, 3, 5, 15, 43, 129, 215, 645

466 : 1, 2, 233, 466

478 : 1, 2, 239, 478

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 813,645,466,478, is 1.

Now, the common factors can be found like this.

813:3x 271

645:3x 5x 43

466:2x 233

478:2x 239

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 116805709980/(1x6)

LCM = 116805709980/6

LCM = 19467618330

Thus, we can understand that the LCM of 813,645,466,478 is 19467618330.
