Given numbers are 817,451,858,257

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

The LCM of 817,451,858,257 is 7386289482.

Find LCM of 817,451,858,257 with Prime Factorization

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

11 x 817 x 41 x 78 x 257 = 7386289482

Therefore, the lowest common multiple of 817,451,858,257 is 7386289482.

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.

817 x 451 x 858 x 257 = 81249184302

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.

817 : 1, 19, 43, 817

451 : 1, 11, 41, 451

858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858

257 : 1, 257

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 817,451,858,257, is 1.

Now, the common factors can be found like this.

817:19x 43

451:11x 41

858:2x 3x 11x 13

257:257

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

11 = 11

Therefore, the value for common factors is 11.

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 = 81249184302/(1x11)

LCM = 81249184302/11

LCM = 7386289482

Thus, we can understand that the LCM of 817,451,858,257 is 7386289482.
