Given numbers are 817,344,878,790

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

The LCM of 817,344,878,790 is 1133375080.

Find LCM of 817,344,878,790 with Prime Factorization

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

2 x 43 x 19 x 4 x 439 x 395 = 1133375080

Therefore, the lowest common multiple of 817,344,878,790 is 1133375080.

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.

817 x 344 x 878 x 790 = 194940513760

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.

817 : 1, 19, 43, 817

344 : 1, 2, 4, 8, 43, 86, 172, 344

878 : 1, 2, 439, 878

790 : 1, 2, 5, 10, 79, 158, 395, 790

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 817,344,878,790, is 1.

Now, the common factors can be found like this.

817:19x 43

344:2x 2x 2x 43

878:2x 439

790:2x 5x 79

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

2x 2x 43 = 172

Therefore, the value for common factors is 172.

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 = 194940513760/(1x172)

LCM = 194940513760/172

LCM = 1133375080

Thus, we can understand that the LCM of 817,344,878,790 is 1133375080.
