Given numbers are 347,382,608,642,991

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

The LCM of 347,382,608,642,991 is 12818733190176.

Find LCM of 347,382,608,642,991 with Prime Factorization

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

2 x 347 x 191 x 304 x 321 x 991 = 12818733190176

Therefore, the lowest common multiple of 347,382,608,642,991 is 12818733190176.

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.

347 x 382 x 608 x 642 x 991 = 51274932760704

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.

347 : 1, 347

382 : 1, 2, 191, 382

608 : 1, 2, 4, 8, 16, 19, 32, 38, 76, 152, 304, 608

642 : 1, 2, 3, 6, 107, 214, 321, 642

991 : 1, 991

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 347,382,608,642,991, is 1.

Now, the common factors can be found like this.

347:347

382:2x 191

608:2x 2x 2x 2x 2x 19

642:2x 3x 107

991:991

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 51274932760704/(1x4)

LCM = 51274932760704/4

LCM = 12818733190176

Thus, we can understand that the LCM of 347,382,608,642,991 is 12818733190176.
