Given numbers are 128,873,668,785

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

The LCM of 128,873,668,785 is 14649079680.

Find LCM of 128,873,668,785 with Prime Factorization

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

2 x 2 x 32 x 873 x 167 x 785 = 14649079680

Therefore, the lowest common multiple of 128,873,668,785 is 14649079680.

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 873 x 668 x 785 = 58596318720

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

873 : 1, 3, 9, 97, 291, 873

668 : 1, 2, 4, 167, 334, 668

785 : 1, 5, 157, 785

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,873,668,785, is 1.

Now, the common factors can be found like this.

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

873:3x 3x 97

668:2x 2x 167

785:5x 157

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 58596318720/(1x4)

LCM = 58596318720/4

LCM = 14649079680

Thus, we can understand that the LCM of 128,873,668,785 is 14649079680.
