Given numbers are 830,699,447,639

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

The LCM of 830,699,447,639 is 18412855290.

Find LCM of 830,699,447,639 with Prime Factorization

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

3 x 830 x 233 x 149 x 213 = 18412855290

Therefore, the lowest common multiple of 830,699,447,639 is 18412855290.

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.

830 x 699 x 447 x 639 = 165715697610

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.

830 : 1, 2, 5, 10, 83, 166, 415, 830

699 : 1, 3, 233, 699

447 : 1, 3, 149, 447

639 : 1, 3, 9, 71, 213, 639

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 830,699,447,639, is 1.

Now, the common factors can be found like this.

830:2x 5x 83

699:3x 233

447:3x 149

639:3x 3x 71

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

3x 3 = 9

Therefore, the value for common factors is 9.

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 = 165715697610/(1x9)

LCM = 165715697610/9

LCM = 18412855290

Thus, we can understand that the LCM of 830,699,447,639 is 18412855290.
