Given numbers are 344,646,391,831

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

The LCM of 344,646,391,831 is 2123683656.

Find LCM of 344,646,391,831 with Prime Factorization

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

2 x 17 x 172 x 19 x 23 x 831 = 2123683656

Therefore, the lowest common multiple of 344,646,391,831 is 2123683656.

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.

344 x 646 x 391 x 831 = 72205244304

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.

344 : 1, 2, 4, 8, 43, 86, 172, 344

646 : 1, 2, 17, 19, 34, 38, 323, 646

391 : 1, 17, 23, 391

831 : 1, 3, 277, 831

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 344,646,391,831, is 1.

Now, the common factors can be found like this.

344:2x 2x 2x 43

646:2x 17x 19

391:17x 23

831:3x 277

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

2x 17 = 34

Therefore, the value for common factors is 34.

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 = 72205244304/(1x34)

LCM = 72205244304/34

LCM = 2123683656

Thus, we can understand that the LCM of 344,646,391,831 is 2123683656.
