Given numbers are 128,888,778,310,186

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

The LCM of 128,888,778,310,186 is 856671360.

Find LCM of 128,888,778,310,186 with Prime Factorization

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

2 x 2 x 2 x 3 x 31 x 16 x 37 x 389 x 5 x 1 = 856671360

Therefore, the lowest common multiple of 128,888,778,310,186 is 856671360.

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 888 x 778 x 310 x 186 = 5098907934720

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

888 : 1, 2, 3, 4, 6, 8, 12, 24, 37, 74, 111, 148, 222, 296, 444, 888

778 : 1, 2, 389, 778

310 : 1, 2, 5, 10, 31, 62, 155, 310

186 : 1, 2, 3, 6, 31, 62, 93, 186

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,888,778,310,186, is 2.

Now, the common factors can be found like this.

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

888:2x 2x 2x 3x 37

778:2x 389

310:2x 5x 31

186:2x 3x 31

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 31 = 2976

Therefore, the value for common factors is 2976.

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 = 5098907934720/(2x2976)

LCM = 5098907934720/5952

LCM = 856671360

Thus, we can understand that the LCM of 128,888,778,310,186 is 856671360.
