Given numbers are 128,834,516,207,545

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

The LCM of 128,834,516,207,545 is 86309792640.

Find LCM of 128,834,516,207,545 with Prime Factorization

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

2 x 2 x 3 x 32 x 139 x 43 x 69 x 545 = 86309792640

Therefore, the lowest common multiple of 128,834,516,207,545 is 86309792640.

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.

128 x 834 x 516 x 207 x 545 = 6214305070080

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.

128 : 1, 2, 4, 8, 16, 32, 64, 128

834 : 1, 2, 3, 6, 139, 278, 417, 834

516 : 1, 2, 3, 4, 6, 12, 43, 86, 129, 172, 258, 516

207 : 1, 3, 9, 23, 69, 207

545 : 1, 5, 109, 545

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,834,516,207,545, is 1.

Now, the common factors can be found like this.

128:2x 2x 2x 2x 2x 2x 2

834:2x 3x 139

516:2x 2x 3x 43

207:3x 3x 23

545:5x 109

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 3x 3 = 72

Therefore, the value for common factors is 72.

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 = 6214305070080/(1x72)

LCM = 6214305070080/72

LCM = 86309792640

Thus, we can understand that the LCM of 128,834,516,207,545 is 86309792640.
