Given numbers are 437,891,239,391,138

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

The LCM of 437,891,239,391,138 is 3163996242.

Find LCM of 437,891,239,391,138 with Prime Factorization

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

3 x 23 x 19 x 297 x 239 x 17 x 2 = 3163996242

Therefore, the lowest common multiple of 437,891,239,391,138 is 3163996242.

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.

437 x 891 x 239 x 391 x 138 = 5021262036054

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.

437 : 1, 19, 23, 437

891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891

239 : 1, 239

391 : 1, 17, 23, 391

138 : 1, 2, 3, 6, 23, 46, 69, 138

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 437,891,239,391,138, is 1.

Now, the common factors can be found like this.

437:19x 23

891:3x 3x 3x 3x 11

239:239

391:17x 23

138:2x 3x 23

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

3x 23x 23 = 1587

Therefore, the value for common factors is 1587.

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 = 5021262036054/(1x1587)

LCM = 5021262036054/1587

LCM = 3163996242

Thus, we can understand that the LCM of 437,891,239,391,138 is 3163996242.
