Given numbers are 991,715,338,999

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

The LCM of 991,715,338,999 is 18404267310.

Find LCM of 991,715,338,999 with Prime Factorization

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

13 x 991 x 55 x 26 x 999 = 18404267310

Therefore, the lowest common multiple of 991,715,338,999 is 18404267310.

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.

991 x 715 x 338 x 999 = 239255475030

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.

991 : 1, 991

715 : 1, 5, 11, 13, 55, 65, 143, 715

338 : 1, 2, 13, 26, 169, 338

999 : 1, 3, 9, 27, 37, 111, 333, 999

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 991,715,338,999, is 1.

Now, the common factors can be found like this.

991:991

715:5x 11x 13

338:2x 13x 13

999:3x 3x 3x 37

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

13 = 13

Therefore, the value for common factors is 13.

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 = 239255475030/(1x13)

LCM = 239255475030/13

LCM = 18404267310

Thus, we can understand that the LCM of 991,715,338,999 is 18404267310.
