Given numbers are 618,612,912,408

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

The LCM of 618,612,912,408 is 4790736.

Find LCM of 618,612,912,408 with Prime Factorization

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

2 x 2 x 2 x 3 x 17 x 103 x 1 x 38 x 3 = 4790736

Therefore, the lowest common multiple of 618,612,912,408 is 4790736.

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.

618 x 612 x 912 x 408 = 140732660736

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.

618 : 1, 2, 3, 6, 103, 206, 309, 618

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

912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912

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

6 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 618,612,912,408, is 6.

Now, the common factors can be found like this.

618:2x 3x 103

612:2x 2x 3x 3x 17

912:2x 2x 2x 2x 3x 19

408:2x 2x 2x 3x 17

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 3x 3x 17 = 4896

Therefore, the value for common factors is 4896.

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 = 140732660736/(6x4896)

LCM = 140732660736/29376

LCM = 4790736

Thus, we can understand that the LCM of 618,612,912,408 is 4790736.
