Given numbers are 857,143,398,821,857

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

The LCM of 857,143,398,821,857 is 40044519658.

Find LCM of 857,143,398,821,857 with Prime Factorization

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

857 x 1 x 143 x 398 x 821 x 1 = 40044519658

Therefore, the lowest common multiple of 857,143,398,821,857 is 40044519658.

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.

857 x 143 x 398 x 821 x 857 = 34318153346906

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.

857 : 1, 857

143 : 1, 11, 13, 143

398 : 1, 2, 199, 398

821 : 1, 821

857 : 1, 857

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 857,143,398,821,857, is 1.

Now, the common factors can be found like this.

857:857

143:11x 13

398:2x 199

821:821

857:857

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

857 = 857

Therefore, the value for common factors is 857.

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 = 34318153346906/(1x857)

LCM = 34318153346906/857

LCM = 40044519658

Thus, we can understand that the LCM of 857,143,398,821,857 is 40044519658.
