Given numbers are 864,778,395,818

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

The LCM of 864,778,395,818 is 54297989280.

Find LCM of 864,778,395,818 with Prime Factorization

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

2 x 432 x 389 x 395 x 409 = 54297989280

Therefore, the lowest common multiple of 864,778,395,818 is 54297989280.

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.

864 x 778 x 395 x 818 = 217191957120

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.

864 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 32, 36, 48, 54, 72, 96, 108, 144, 216, 288, 432, 864

778 : 1, 2, 389, 778

395 : 1, 5, 79, 395

818 : 1, 2, 409, 818

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 864,778,395,818, is 1.

Now, the common factors can be found like this.

864:2x 2x 2x 2x 2x 3x 3x 3

778:2x 389

395:5x 79

818:2x 409

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 217191957120/(1x4)

LCM = 217191957120/4

LCM = 54297989280

Thus, we can understand that the LCM of 864,778,395,818 is 54297989280.
