Given numbers are 815,447,436,992

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

The LCM of 815,447,436,992 is 39391571040.

Find LCM of 815,447,436,992 with Prime Factorization

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

2 x 2 x 815 x 447 x 109 x 248 = 39391571040

Therefore, the lowest common multiple of 815,447,436,992 is 39391571040.

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.

815 x 447 x 436 x 992 = 157566284160

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.

815 : 1, 5, 163, 815

447 : 1, 3, 149, 447

436 : 1, 2, 4, 109, 218, 436

992 : 1, 2, 4, 8, 16, 31, 32, 62, 124, 248, 496, 992

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 815,447,436,992, is 1.

Now, the common factors can be found like this.

815:5x 163

447:3x 149

436:2x 2x 109

992:2x 2x 2x 2x 2x 31

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 = 157566284160/(1x4)

LCM = 157566284160/4

LCM = 39391571040

Thus, we can understand that the LCM of 815,447,436,992 is 39391571040.
