Given numbers are 391,856,271,871,845

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

The LCM of 391,856,271,871,845 is 5135128604840.

Find LCM of 391,856,271,871,845 with Prime Factorization

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

13 x 391 x 856 x 271 x 67 x 65 = 5135128604840

Therefore, the lowest common multiple of 391,856,271,871,845 is 5135128604840.

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 856 x 271 x 871 x 845 = 66756671862920

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

856 : 1, 2, 4, 8, 107, 214, 428, 856

271 : 1, 271

871 : 1, 13, 67, 871

845 : 1, 5, 13, 65, 169, 845

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,856,271,871,845, is 1.

Now, the common factors can be found like this.

391:17x 23

856:2x 2x 2x 107

271:271

871:13x 67

845:5x 13x 13

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

13 = 13

Therefore, the value for common factors is 13.

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 = 66756671862920/(1x13)

LCM = 66756671862920/13

LCM = 5135128604840

Thus, we can understand that the LCM of 391,856,271,871,845 is 5135128604840.
