Given numbers are 391,872,391,137

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

The LCM of 391,872,391,137 is 46710424.

Find LCM of 391,872,391,137 with Prime Factorization

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

17 x 23 x 1 x 872 x 1 x 137 = 46710424

Therefore, the lowest common multiple of 391,872,391,137 is 46710424.

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.

391 x 872 x 391 x 137 = 18263775784

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.

391 : 1, 17, 23, 391

872 : 1, 2, 4, 8, 109, 218, 436, 872

391 : 1, 17, 23, 391

137 : 1, 137

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,872,391,137, is 1.

Now, the common factors can be found like this.

391:17x 23

872:2x 2x 2x 109

391:17x 23

137:137

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

17x 23 = 391

Therefore, the value for common factors is 391.

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 = 18263775784/(1x391)

LCM = 18263775784/391

LCM = 46710424

Thus, we can understand that the LCM of 391,872,391,137 is 46710424.
