Given numbers are 816,409,278,286

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

The LCM of 816,409,278,286 is 6633829488.

Find LCM of 816,409,278,286 with Prime Factorization

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

2 x 408 x 409 x 139 x 143 = 6633829488

Therefore, the lowest common multiple of 816,409,278,286 is 6633829488.

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.

816 x 409 x 278 x 286 = 26535317952

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.

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

409 : 1, 409

278 : 1, 2, 139, 278

286 : 1, 2, 11, 13, 22, 26, 143, 286

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 816,409,278,286, is 1.

Now, the common factors can be found like this.

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

409:409

278:2x 139

286:2x 11x 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 = 26535317952/(1x4)

LCM = 26535317952/4

LCM = 6633829488

Thus, we can understand that the LCM of 816,409,278,286 is 6633829488.
