Given numbers are 861,474,623,336,818

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

The LCM of 861,474,623,336,818 is 39615353904.

Find LCM of 861,474,623,336,818 with Prime Factorization

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

2 x 3 x 7 x 41 x 79 x 89 x 8 x 409 = 39615353904

Therefore, the lowest common multiple of 861,474,623,336,818 is 39615353904.

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.

861 x 474 x 623 x 336 x 818 = 69881484286656

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.

861 : 1, 3, 7, 21, 41, 123, 287, 861

474 : 1, 2, 3, 6, 79, 158, 237, 474

623 : 1, 7, 89, 623

336 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 42, 48, 56, 84, 112, 168, 336

818 : 1, 2, 409, 818

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 861,474,623,336,818, is 1.

Now, the common factors can be found like this.

861:3x 7x 41

474:2x 3x 79

623:7x 89

336:2x 2x 2x 2x 3x 7

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 2x 3x 3x 7x 7 = 1764

Therefore, the value for common factors is 1764.

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 = 69881484286656/(1x1764)

LCM = 69881484286656/1764

LCM = 39615353904

Thus, we can understand that the LCM of 861,474,623,336,818 is 39615353904.
