Given numbers are 216,381,553,815,685

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

The LCM of 216,381,553,815,685 is 1693794737880.

Find LCM of 216,381,553,815,685 with Prime Factorization

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

3 x 5 x 72 x 127 x 553 x 163 x 137 = 1693794737880

Therefore, the lowest common multiple of 216,381,553,815,685 is 1693794737880.

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.

216 x 381 x 553 x 815 x 685 = 25406921068200

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.

216 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 108, 216

381 : 1, 3, 127, 381

553 : 1, 7, 79, 553

815 : 1, 5, 163, 815

685 : 1, 5, 137, 685

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 216,381,553,815,685, is 1.

Now, the common factors can be found like this.

216:2x 2x 2x 3x 3x 3

381:3x 127

553:7x 79

815:5x 163

685:5x 137

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

3x 5 = 15

Therefore, the value for common factors is 15.

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 = 25406921068200/(1x15)

LCM = 25406921068200/15

LCM = 1693794737880

Thus, we can understand that the LCM of 216,381,553,815,685 is 1693794737880.
