Given numbers are 815,217,682,403

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

The LCM of 815,217,682,403 is 50580530.

Find LCM of 815,217,682,403 with Prime Factorization

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

31 x 815 x 7 x 22 x 13 = 50580530

Therefore, the lowest common multiple of 815,217,682,403 is 50580530.

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 217 x 682 x 403 = 48607889330

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

217 : 1, 7, 31, 217

682 : 1, 2, 11, 22, 31, 62, 341, 682

403 : 1, 13, 31, 403

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 815,217,682,403, is 1.

Now, the common factors can be found like this.

815:5x 163

217:7x 31

682:2x 11x 31

403:13x 31

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

31x 31 = 961

Therefore, the value for common factors is 961.

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 = 48607889330/(1x961)

LCM = 48607889330/961

LCM = 50580530

Thus, we can understand that the LCM of 815,217,682,403 is 50580530.
