Given numbers are 391,727,218,478

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

The LCM of 391,727,218,478 is 14810358214.

Find LCM of 391,727,218,478 with Prime Factorization

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

2 x 391 x 727 x 109 x 239 = 14810358214

Therefore, the lowest common multiple of 391,727,218,478 is 14810358214.

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 727 x 218 x 478 = 29620716428

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

727 : 1, 727

218 : 1, 2, 109, 218

478 : 1, 2, 239, 478

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,727,218,478, is 1.

Now, the common factors can be found like this.

391:17x 23

727:727

218:2x 109

478:2x 239

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

2 = 2

Therefore, the value for common factors is 2.

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 = 29620716428/(1x2)

LCM = 29620716428/2

LCM = 14810358214

Thus, we can understand that the LCM of 391,727,218,478 is 14810358214.
