Given numbers are 645,214,328,449

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

The LCM of 645,214,328,449 is 10163977080.

Find LCM of 645,214,328,449 with Prime Factorization

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

2 x 645 x 107 x 164 x 449 = 10163977080

Therefore, the lowest common multiple of 645,214,328,449 is 10163977080.

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.

645 x 214 x 328 x 449 = 20327954160

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.

645 : 1, 3, 5, 15, 43, 129, 215, 645

214 : 1, 2, 107, 214

328 : 1, 2, 4, 8, 41, 82, 164, 328

449 : 1, 449

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 645,214,328,449, is 1.

Now, the common factors can be found like this.

645:3x 5x 43

214:2x 107

328:2x 2x 2x 41

449:449

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2 = 2

Therefore, the value for common factors is 2.

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 = 20327954160/(1x2)

LCM = 20327954160/2

LCM = 10163977080

Thus, we can understand that the LCM of 645,214,328,449 is 10163977080.
