Given numbers are 855,409,242,910

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

The LCM of 855,409,242,910 is 7700983290.

Find LCM of 855,409,242,910 with Prime Factorization

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

2 x 5 x 171 x 409 x 121 x 91 = 7700983290

Therefore, the lowest common multiple of 855,409,242,910 is 7700983290.

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 409 x 242 x 910 = 77009832900

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

409 : 1, 409

242 : 1, 2, 11, 22, 121, 242

910 : 1, 2, 5, 7, 10, 13, 14, 26, 35, 65, 70, 91, 130, 182, 455, 910

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 855,409,242,910, is 1.

Now, the common factors can be found like this.

855:3x 3x 5x 19

409:409

242:2x 11x 11

910:2x 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 5 = 10

Therefore, the value for common factors is 10.

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 = 77009832900/(1x10)

LCM = 77009832900/10

LCM = 7700983290

Thus, we can understand that the LCM of 855,409,242,910 is 7700983290.
