Given numbers are 128,942,384,857

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

The LCM of 128,942,384,857 is 51666816.

Find LCM of 128,942,384,857 with Prime Factorization

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

2 x 2 x 2 x 2 x 2 x 2 x 2 x 3 x 1 x 157 x 1 x 857 = 51666816

Therefore, the lowest common multiple of 128,942,384,857 is 51666816.

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 942 x 384 x 857 = 39680114688

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

942 : 1, 2, 3, 6, 157, 314, 471, 942

384 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 384

857 : 1, 857

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,942,384,857, is 1.

Now, the common factors can be found like this.

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

942:2x 3x 157

384:2x 2x 2x 2x 2x 2x 2x 3

857:857

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 2x 2x 2x 3 = 768

Therefore, the value for common factors is 768.

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 = 39680114688/(1x768)

LCM = 39680114688/768

LCM = 51666816

Thus, we can understand that the LCM of 128,942,384,857 is 51666816.
