Given numbers are 286,351,208,455

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

The LCM of 286,351,208,455 is 2162160.

Find LCM of 286,351,208,455 with Prime Factorization

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

2 x 13 x 11 x 27 x 8 x 35 = 2162160

Therefore, the lowest common multiple of 286,351,208,455 is 2162160.

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.

286 x 351 x 208 x 455 = 9500531040

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.

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

351 : 1, 3, 9, 13, 27, 39, 117, 351

208 : 1, 2, 4, 8, 13, 16, 26, 52, 104, 208

455 : 1, 5, 7, 13, 35, 65, 91, 455

13 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 286,351,208,455, is 13.

Now, the common factors can be found like this.

286:2x 11x 13

351:3x 3x 3x 13

208:2x 2x 2x 2x 13

455:5x 7x 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 13x 13 = 338

Therefore, the value for common factors is 338.

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 = 9500531040/(13x338)

LCM = 9500531040/4394

LCM = 2162160

Thus, we can understand that the LCM of 286,351,208,455 is 2162160.
