Given numbers are 815,260,721,195,125

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

The LCM of 815,260,721,195,125 is 2291698500.

Find LCM of 815,260,721,195,125 with Prime Factorization

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

5 x 13 x 163 x 4 x 721 x 3 x 25 = 2291698500

Therefore, the lowest common multiple of 815,260,721,195,125 is 2291698500.

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.

815 x 260 x 721 x 195 x 125 = 3724010062500

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.

815 : 1, 5, 163, 815

260 : 1, 2, 4, 5, 10, 13, 20, 26, 52, 65, 130, 260

721 : 1, 7, 103, 721

195 : 1, 3, 5, 13, 15, 39, 65, 195

125 : 1, 5, 25, 125

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 815,260,721,195,125, is 1.

Now, the common factors can be found like this.

815:5x 163

260:2x 2x 5x 13

721:7x 103

195:3x 5x 13

125:5x 5x 5

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

5x 5x 5x 13 = 1625

Therefore, the value for common factors is 1625.

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 = 3724010062500/(1x1625)

LCM = 3724010062500/1625

LCM = 2291698500

Thus, we can understand that the LCM of 815,260,721,195,125 is 2291698500.
