Given numbers are 612,408,916,816,386

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

The LCM of 612,408,916,816,386 is 108194256.

Find LCM of 612,408,916,816,386 with Prime Factorization

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

2 x 2 x 2 x 3 x 17 x 1 x 3 x 229 x 2 x 193 = 108194256

Therefore, the lowest common multiple of 612,408,916,816,386 is 108194256.

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.

612 x 408 x 916 x 816 x 386 = 72041794523136

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.

612 : 1, 2, 3, 4, 6, 9, 12, 17, 18, 34, 36, 51, 68, 102, 153, 204, 306, 612

408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408

916 : 1, 2, 4, 229, 458, 916

816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816

386 : 1, 2, 193, 386

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 612,408,916,816,386, is 2.

Now, the common factors can be found like this.

612:2x 2x 3x 3x 17

408:2x 2x 2x 3x 17

916:2x 2x 229

816:2x 2x 2x 2x 3x 17

386:2x 193

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 2x 2x 2x 2x 2x 3x 3x 17x 17 = 332928

Therefore, the value for common factors is 332928.

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 = 72041794523136/(2x332928)

LCM = 72041794523136/665856

LCM = 108194256

Thus, we can understand that the LCM of 612,408,916,816,386 is 108194256.
