Given numbers are 845,409,278,871

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

The LCM of 845,409,278,871 is 6437238730.

Find LCM of 845,409,278,871 with Prime Factorization

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

13 x 65 x 409 x 278 x 67 = 6437238730

Therefore, the lowest common multiple of 845,409,278,871 is 6437238730.

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.

845 x 409 x 278 x 871 = 83684103490

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.

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

409 : 1, 409

278 : 1, 2, 139, 278

871 : 1, 13, 67, 871

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 845,409,278,871, is 1.

Now, the common factors can be found like this.

845:5x 13x 13

409:409

278:2x 139

871:13x 67

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 = 83684103490/(1x13)

LCM = 83684103490/13

LCM = 6437238730

Thus, we can understand that the LCM of 845,409,278,871 is 6437238730.
