Given numbers are 247,936,819,845

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

The LCM of 247,936,819,845 is 8091720.

Find LCM of 247,936,819,845 with Prime Factorization

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

3 x 3 x 13 x 19 x 8 x 7 x 65 = 8091720

Therefore, the lowest common multiple of 247,936,819,845 is 8091720.

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.

247 x 936 x 819 x 845 = 159997579560

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.

247 : 1, 13, 19, 247

936 : 1, 2, 3, 4, 6, 8, 9, 12, 13, 18, 24, 26, 36, 39, 52, 72, 78, 104, 117, 156, 234, 312, 468, 936

819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819

845 : 1, 5, 13, 65, 169, 845

13 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 247,936,819,845, is 13.

Now, the common factors can be found like this.

247:13x 19

936:2x 2x 2x 3x 3x 13

819:3x 3x 7x 13

845:5x 13x 13

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

3x 3x 13x 13 = 1521

Therefore, the value for common factors is 1521.

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 = 159997579560/(13x1521)

LCM = 159997579560/19773

LCM = 8091720

Thus, we can understand that the LCM of 247,936,819,845 is 8091720.
