Given numbers are 871,343,411,853,221

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

The LCM of 871,343,411,853,221 is 1780541290983.

Find LCM of 871,343,411,853,221 with Prime Factorization

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

13 x 67 x 343 x 411 x 853 x 17 = 1780541290983

Therefore, the lowest common multiple of 871,343,411,853,221 is 1780541290983.

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.

871 x 343 x 411 x 853 x 221 = 23147036782779

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.

871 : 1, 13, 67, 871

343 : 1, 7, 49, 343

411 : 1, 3, 137, 411

853 : 1, 853

221 : 1, 13, 17, 221

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 871,343,411,853,221, is 1.

Now, the common factors can be found like this.

871:13x 67

343:7x 7x 7

411:3x 137

853:853

221:13x 17

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

13 = 13

Therefore, the value for common factors is 13.

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 = 23147036782779/(1x13)

LCM = 23147036782779/13

LCM = 1780541290983

Thus, we can understand that the LCM of 871,343,411,853,221 is 1780541290983.
