Given numbers are 855,821,306,406

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

The LCM of 855,821,306,406 is 4844893410.

Find LCM of 855,821,306,406 with Prime Factorization

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

2 x 3 x 3 x 95 x 821 x 17 x 203 = 4844893410

Therefore, the lowest common multiple of 855,821,306,406 is 4844893410.

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.

855 x 821 x 306 x 406 = 87208081380

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.

855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855

821 : 1, 821

306 : 1, 2, 3, 6, 9, 17, 18, 34, 51, 102, 153, 306

406 : 1, 2, 7, 14, 29, 58, 203, 406

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 855,821,306,406, is 1.

Now, the common factors can be found like this.

855:3x 3x 5x 19

821:821

306:2x 3x 3x 17

406:2x 7x 29

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

2x 3x 3 = 18

Therefore, the value for common factors is 18.

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 = 87208081380/(1x18)

LCM = 87208081380/18

LCM = 4844893410

Thus, we can understand that the LCM of 855,821,306,406 is 4844893410.
