Given numbers are 818,217,538,390

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

The LCM of 818,217,538,390 is 9311077230.

Find LCM of 818,217,538,390 with Prime Factorization

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

2 x 409 x 217 x 269 x 195 = 9311077230

Therefore, the lowest common multiple of 818,217,538,390 is 9311077230.

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.

818 x 217 x 538 x 390 = 37244308920

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.

818 : 1, 2, 409, 818

217 : 1, 7, 31, 217

538 : 1, 2, 269, 538

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 818,217,538,390, is 1.

Now, the common factors can be found like this.

818:2x 409

217:7x 31

538:2x 269

390:2x 3x 5x 13

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 = 37244308920/(1x4)

LCM = 37244308920/4

LCM = 9311077230

Thus, we can understand that the LCM of 818,217,538,390 is 9311077230.
