Given numbers are 861,291,702,407,863

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

The LCM of 861,291,702,407,863 is 6864295135698.

Find LCM of 861,291,702,407,863 with Prime Factorization

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

3 x 287 x 97 x 234 x 407 x 863 = 6864295135698

Therefore, the lowest common multiple of 861,291,702,407,863 is 6864295135698.

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.

861 x 291 x 702 x 407 x 863 = 61778656221282

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.

861 : 1, 3, 7, 21, 41, 123, 287, 861

291 : 1, 3, 97, 291

702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702

407 : 1, 11, 37, 407

863 : 1, 863

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 861,291,702,407,863, is 1.

Now, the common factors can be found like this.

861:3x 7x 41

291:3x 97

702:2x 3x 3x 3x 13

407:11x 37

863:863

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

3x 3 = 9

Therefore, the value for common factors is 9.

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 = 61778656221282/(1x9)

LCM = 61778656221282/9

LCM = 6864295135698

Thus, we can understand that the LCM of 861,291,702,407,863 is 6864295135698.
