Given numbers are 128,316,208,643

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

The LCM of 128,316,208,643 is 84526208.

Find LCM of 128,316,208,643 with Prime Factorization

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

2 x 2 x 2 x 2 x 8 x 79 x 13 x 643 = 84526208

Therefore, the lowest common multiple of 128,316,208,643 is 84526208.

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 316 x 208 x 643 = 5409677312

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

316 : 1, 2, 4, 79, 158, 316

208 : 1, 2, 4, 8, 13, 16, 26, 52, 104, 208

643 : 1, 643

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,316,208,643, is 1.

Now, the common factors can be found like this.

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

316:2x 2x 79

208:2x 2x 2x 2x 13

643:643

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 2 = 64

Therefore, the value for common factors is 64.

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 = 5409677312/(1x64)

LCM = 5409677312/64

LCM = 84526208

Thus, we can understand that the LCM of 128,316,208,643 is 84526208.
