Given numbers are 445,390,343,296,665

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

The LCM of 445,390,343,296,665 is 33478350360.

Find LCM of 445,390,343,296,665 with Prime Factorization

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

2 x 5 x 7 x 89 x 39 x 49 x 148 x 19 = 33478350360

Therefore, the lowest common multiple of 445,390,343,296,665 is 33478350360.

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.

445 x 390 x 343 x 296 x 665 = 11717422626000

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.

445 : 1, 5, 89, 445

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

343 : 1, 7, 49, 343

296 : 1, 2, 4, 8, 37, 74, 148, 296

665 : 1, 5, 7, 19, 35, 95, 133, 665

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 445,390,343,296,665, is 1.

Now, the common factors can be found like this.

445:5x 89

390:2x 3x 5x 13

343:7x 7x 7

296:2x 2x 2x 37

665:5x 7x 19

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

2x 5x 5x 7 = 350

Therefore, the value for common factors is 350.

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 = 11717422626000/(1x350)

LCM = 11717422626000/350

LCM = 33478350360

Thus, we can understand that the LCM of 445,390,343,296,665 is 33478350360.
