Given numbers are 391,521,813,271

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

The LCM of 391,521,813,271 is 165617043.

Find LCM of 391,521,813,271 with Prime Factorization

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

271 x 391 x 521 x 3 x 1 = 165617043

Therefore, the lowest common multiple of 391,521,813,271 is 165617043.

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 521 x 813 x 271 = 44882218653

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

521 : 1, 521

813 : 1, 3, 271, 813

271 : 1, 271

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,521,813,271, is 1.

Now, the common factors can be found like this.

391:17x 23

521:521

813:3x 271

271:271

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

271 = 271

Therefore, the value for common factors is 271.

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 = 44882218653/(1x271)

LCM = 44882218653/271

LCM = 165617043

Thus, we can understand that the LCM of 391,521,813,271 is 165617043.
