Given numbers are 815,427,959,475,840

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

The LCM of 815,427,959,475,840 is 108702841800.

Find LCM of 815,427,959,475,840 with Prime Factorization

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

5 x 7 x 163 x 61 x 137 x 95 x 24 = 108702841800

Therefore, the lowest common multiple of 815,427,959,475,840 is 108702841800.

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 427 x 959 x 475 x 840 = 133160981205000

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

427 : 1, 7, 61, 427

959 : 1, 7, 137, 959

475 : 1, 5, 19, 25, 95, 475

840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 815,427,959,475,840, is 1.

Now, the common factors can be found like this.

815:5x 163

427:7x 61

959:7x 137

475:5x 5x 19

840:2x 2x 2x 3x 5x 7

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 7x 7 = 1225

Therefore, the value for common factors is 1225.

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 = 133160981205000/(1x1225)

LCM = 133160981205000/1225

LCM = 108702841800

Thus, we can understand that the LCM of 815,427,959,475,840 is 108702841800.
