Given numbers are 918,804,644,408

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

The LCM of 918,804,644,408 is 39609864.

Find LCM of 918,804,644,408 with Prime Factorization

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

2 x 2 x 3 x 17 x 9 x 67 x 161 x 2 = 39609864

Therefore, the lowest common multiple of 918,804,644,408 is 39609864.

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.

918 x 804 x 644 x 408 = 193929894144

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.

918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918

804 : 1, 2, 3, 4, 6, 12, 67, 134, 201, 268, 402, 804

644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644

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

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 918,804,644,408, is 2.

Now, the common factors can be found like this.

918:2x 3x 3x 3x 17

804:2x 2x 3x 67

644:2x 2x 7x 23

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 3x 3x 17 = 2448

Therefore, the value for common factors is 2448.

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 = 193929894144/(2x2448)

LCM = 193929894144/4896

LCM = 39609864

Thus, we can understand that the LCM of 918,804,644,408 is 39609864.
