Given numbers are 871,556,838,418

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

The LCM of 871,556,838,418 is 42408533596.

Find LCM of 871,556,838,418 with Prime Factorization

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

2 x 871 x 278 x 419 x 209 = 42408533596

Therefore, the lowest common multiple of 871,556,838,418 is 42408533596.

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 556 x 838 x 418 = 169634134384

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

556 : 1, 2, 4, 139, 278, 556

838 : 1, 2, 419, 838

418 : 1, 2, 11, 19, 22, 38, 209, 418

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 871,556,838,418, is 1.

Now, the common factors can be found like this.

871:13x 67

556:2x 2x 139

838:2x 419

418:2x 11x 19

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 169634134384/(1x4)

LCM = 169634134384/4

LCM = 42408533596

Thus, we can understand that the LCM of 871,556,838,418 is 42408533596.
