Given numbers are 115,408,920,991,820

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

The LCM of 115,408,920,991,820 is 1906406520.

Find LCM of 115,408,920,991,820 with Prime Factorization

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

2 x 2 x 2 x 5 x 23 x 1 x 51 x 1 x 991 x 41 = 1906406520

Therefore, the lowest common multiple of 115,408,920,991,820 is 1906406520.

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.

115 x 408 x 920 x 991 x 820 = 35077879968000

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.

115 : 1, 5, 23, 115

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

920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920

991 : 1, 991

820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 115,408,920,991,820, is 1.

Now, the common factors can be found like this.

115:5x 23

408:2x 2x 2x 3x 17

920:2x 2x 2x 5x 23

991:991

820:2x 2x 5x 41

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 5x 5x 23 = 18400

Therefore, the value for common factors is 18400.

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 = 35077879968000/(1x18400)

LCM = 35077879968000/18400

LCM = 1906406520

Thus, we can understand that the LCM of 115,408,920,991,820 is 1906406520.
