Given numbers are 318,128,388,439

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

The LCM of 318,128,388,439 is 866649216.

Find LCM of 318,128,388,439 with Prime Factorization

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

2 x 2 x 159 x 32 x 97 x 439 = 866649216

Therefore, the lowest common multiple of 318,128,388,439 is 866649216.

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.

318 x 128 x 388 x 439 = 6933193728

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.

318 : 1, 2, 3, 6, 53, 106, 159, 318

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

388 : 1, 2, 4, 97, 194, 388

439 : 1, 439

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 318,128,388,439, is 1.

Now, the common factors can be found like this.

318:2x 3x 53

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

388:2x 2x 97

439:439

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 2 = 8

Therefore, the value for common factors is 8.

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 = 6933193728/(1x8)

LCM = 6933193728/8

LCM = 866649216

Thus, we can understand that the LCM of 318,128,388,439 is 866649216.
