Given numbers are 646,871,614,272,547

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

The LCM of 646,871,614,272,547 is 755903509712.

Find LCM of 646,871,614,272,547 with Prime Factorization

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

2 x 17 x 19 x 871 x 307 x 8 x 547 = 755903509712

Therefore, the lowest common multiple of 646,871,614,272,547 is 755903509712.

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.

646 x 871 x 614 x 272 x 547 = 51401438660416

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.

646 : 1, 2, 17, 19, 34, 38, 323, 646

871 : 1, 13, 67, 871

614 : 1, 2, 307, 614

272 : 1, 2, 4, 8, 16, 17, 34, 68, 136, 272

547 : 1, 547

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,871,614,272,547, is 1.

Now, the common factors can be found like this.

646:2x 17x 19

871:13x 67

614:2x 307

272:2x 2x 2x 2x 17

547:547

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

2x 2x 17 = 68

Therefore, the value for common factors is 68.

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 = 51401438660416/(1x68)

LCM = 51401438660416/68

LCM = 755903509712

Thus, we can understand that the LCM of 646,871,614,272,547 is 755903509712.
