Given numbers are 721,815,800,317

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

The LCM of 721,815,800,317 is 29803832800.

Find LCM of 721,815,800,317 with Prime Factorization

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

5 x 721 x 163 x 160 x 317 = 29803832800

Therefore, the lowest common multiple of 721,815,800,317 is 29803832800.

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.

721 x 815 x 800 x 317 = 149019164000

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.

721 : 1, 7, 103, 721

815 : 1, 5, 163, 815

800 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 32, 40, 50, 80, 100, 160, 200, 400, 800

317 : 1, 317

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,815,800,317, is 1.

Now, the common factors can be found like this.

721:7x 103

815:5x 163

800:2x 2x 2x 2x 2x 5x 5

317:317

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

5 = 5

Therefore, the value for common factors is 5.

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 = 149019164000/(1x5)

LCM = 149019164000/5

LCM = 29803832800

Thus, we can understand that the LCM of 721,815,800,317 is 29803832800.
