Given numbers are 172,996,478,408,660

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

The LCM of 172,996,478,408,660 is 19141118040.

Find LCM of 172,996,478,408,660 with Prime Factorization

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

2 x 2 x 3 x 43 x 83 x 239 x 34 x 55 = 19141118040

Therefore, the lowest common multiple of 172,996,478,408,660 is 19141118040.

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.

172 x 996 x 478 x 408 x 660 = 22050567982080

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.

172 : 1, 2, 4, 43, 86, 172

996 : 1, 2, 3, 4, 6, 12, 83, 166, 249, 332, 498, 996

478 : 1, 2, 239, 478

408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408

660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 172,996,478,408,660, is 2.

Now, the common factors can be found like this.

172:2x 2x 43

996:2x 2x 3x 83

478:2x 239

408:2x 2x 2x 3x 17

660:2x 2x 3x 5x 11

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 2x 2x 2x 2x 3x 3 = 576

Therefore, the value for common factors is 576.

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 = 22050567982080/(2x576)

LCM = 22050567982080/1152

LCM = 19141118040

Thus, we can understand that the LCM of 172,996,478,408,660 is 19141118040.
