Given numbers are 803,815,815,447

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

The LCM of 803,815,815,447 is 292536915.

Find LCM of 803,815,815,447 with Prime Factorization

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

5 x 163 x 803 x 1 x 1 x 447 = 292536915

Therefore, the lowest common multiple of 803,815,815,447 is 292536915.

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.

803 x 815 x 815 x 447 = 238417585725

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.

803 : 1, 11, 73, 803

815 : 1, 5, 163, 815

815 : 1, 5, 163, 815

447 : 1, 3, 149, 447

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 803,815,815,447, is 1.

Now, the common factors can be found like this.

803:11x 73

815:5x 163

815:5x 163

447:3x 149

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

5x 163 = 815

Therefore, the value for common factors is 815.

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 = 238417585725/(1x815)

LCM = 238417585725/815

LCM = 292536915

Thus, we can understand that the LCM of 803,815,815,447 is 292536915.
