Given numbers are 428,388,999,382

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

The LCM of 428,388,999,382 is 7921626444.

Find LCM of 428,388,999,382 with Prime Factorization

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

2 x 2 x 107 x 97 x 999 x 191 = 7921626444

Therefore, the lowest common multiple of 428,388,999,382 is 7921626444.

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.

428 x 388 x 999 x 382 = 63373011552

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.

428 : 1, 2, 4, 107, 214, 428

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

999 : 1, 3, 9, 27, 37, 111, 333, 999

382 : 1, 2, 191, 382

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 428,388,999,382, is 1.

Now, the common factors can be found like this.

428:2x 2x 107

388:2x 2x 97

999:3x 3x 3x 37

382:2x 191

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 = 63373011552/(1x8)

LCM = 63373011552/8

LCM = 7921626444

Thus, we can understand that the LCM of 428,388,999,382 is 7921626444.
