Given numbers are 344,641,634,390

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

The LCM of 344,641,634,390 is 13630454760.

Find LCM of 344,641,634,390 with Prime Factorization

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

2 x 172 x 641 x 317 x 195 = 13630454760

Therefore, the lowest common multiple of 344,641,634,390 is 13630454760.

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 641 x 634 x 390 = 54521819040

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

641 : 1, 641

634 : 1, 2, 317, 634

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 344,641,634,390, is 1.

Now, the common factors can be found like this.

344:2x 2x 2x 43

641:641

634:2x 317

390:2x 3x 5x 13

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 54521819040/(1x4)

LCM = 54521819040/4

LCM = 13630454760

Thus, we can understand that the LCM of 344,641,634,390 is 13630454760.
