Given numbers are 491,914,287,205

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

The LCM of 491,914,287,205 is 643990690.

Find LCM of 491,914,287,205 with Prime Factorization

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

41 x 491 x 914 x 7 x 5 = 643990690

Therefore, the lowest common multiple of 491,914,287,205 is 643990690.

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.

491 x 914 x 287 x 205 = 26403618290

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.

491 : 1, 491

914 : 1, 2, 457, 914

287 : 1, 7, 41, 287

205 : 1, 5, 41, 205

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 491,914,287,205, is 1.

Now, the common factors can be found like this.

491:491

914:2x 457

287:7x 41

205:5x 41

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

41 = 41

Therefore, the value for common factors is 41.

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 = 26403618290/(1x41)

LCM = 26403618290/41

LCM = 643990690

Thus, we can understand that the LCM of 491,914,287,205 is 643990690.
