Given numbers are 163,674,268,443,621

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

The LCM of 163,674,268,443,621 is 4049931015324.

Find LCM of 163,674,268,443,621 with Prime Factorization

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

2 x 163 x 337 x 134 x 443 x 621 = 4049931015324

Therefore, the lowest common multiple of 163,674,268,443,621 is 4049931015324.

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.

163 x 674 x 268 x 443 x 621 = 8099862030648

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.

163 : 1, 163

674 : 1, 2, 337, 674

268 : 1, 2, 4, 67, 134, 268

443 : 1, 443

621 : 1, 3, 9, 23, 27, 69, 207, 621

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 163,674,268,443,621, is 1.

Now, the common factors can be found like this.

163:163

674:2x 337

268:2x 2x 67

443:443

621:3x 3x 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.

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 = 8099862030648/(1x2)

LCM = 8099862030648/2

LCM = 4049931015324

Thus, we can understand that the LCM of 163,674,268,443,621 is 4049931015324.
