Given numbers are 455,863,805,685

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

The LCM of 455,863,805,685 is 1237287415.

Find LCM of 455,863,805,685 with Prime Factorization

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

5 x 7 x 13 x 863 x 23 x 137 = 1237287415

Therefore, the lowest common multiple of 455,863,805,685 is 1237287415.

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.

455 x 863 x 805 x 685 = 216525297625

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.

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

863 : 1, 863

805 : 1, 5, 7, 23, 35, 115, 161, 805

685 : 1, 5, 137, 685

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 455,863,805,685, is 1.

Now, the common factors can be found like this.

455:5x 7x 13

863:863

805:5x 7x 23

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.

5x 5x 7 = 175

Therefore, the value for common factors is 175.

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 = 216525297625/(1x175)

LCM = 216525297625/175

LCM = 1237287415

Thus, we can understand that the LCM of 455,863,805,685 is 1237287415.
