Given numbers are 209,816,386,781,808

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

The LCM of 209,816,386,781,808 is 236033407632.

Find LCM of 209,816,386,781,808 with Prime Factorization

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

2 x 2 x 2 x 11 x 19 x 102 x 193 x 71 x 101 = 236033407632

Therefore, the lowest common multiple of 209,816,386,781,808 is 236033407632.

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.

209 x 816 x 386 x 781 x 808 = 41541879743232

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.

209 : 1, 11, 19, 209

816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816

386 : 1, 2, 193, 386

781 : 1, 11, 71, 781

808 : 1, 2, 4, 8, 101, 202, 404, 808

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 209,816,386,781,808, is 1.

Now, the common factors can be found like this.

209:11x 19

816:2x 2x 2x 2x 3x 17

386:2x 193

781:11x 71

808:2x 2x 2x 101

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

2x 2x 2x 2x 11 = 176

Therefore, the value for common factors is 176.

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 = 41541879743232/(1x176)

LCM = 41541879743232/176

LCM = 236033407632

Thus, we can understand that the LCM of 209,816,386,781,808 is 236033407632.
