Given numbers are 871,598,205,642

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

The LCM of 871,598,205,642 is 2636543130.

Find LCM of 871,598,205,642 with Prime Factorization

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

2 x 13 x 67 x 23 x 205 x 321 = 2636543130

Therefore, the lowest common multiple of 871,598,205,642 is 2636543130.

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 598 x 205 x 642 = 68550121380

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

598 : 1, 2, 13, 23, 26, 46, 299, 598

205 : 1, 5, 41, 205

642 : 1, 2, 3, 6, 107, 214, 321, 642

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 871,598,205,642, is 1.

Now, the common factors can be found like this.

871:13x 67

598:2x 13x 23

205:5x 41

642:2x 3x 107

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

2x 13 = 26

Therefore, the value for common factors is 26.

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 = 68550121380/(1x26)

LCM = 68550121380/26

LCM = 2636543130

Thus, we can understand that the LCM of 871,598,205,642 is 2636543130.
