Given numbers are 871,879,586,421

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

The LCM of 871,879,586,421 is 644642778.

Find LCM of 871,879,586,421 with Prime Factorization

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

293 x 871 x 3 x 2 x 421 = 644642778

Therefore, the lowest common multiple of 871,879,586,421 is 644642778.

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 879 x 586 x 421 = 188880333954

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

879 : 1, 3, 293, 879

586 : 1, 2, 293, 586

421 : 1, 421

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 871,879,586,421, is 1.

Now, the common factors can be found like this.

871:13x 67

879:3x 293

586:2x 293

421:421

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

293 = 293

Therefore, the value for common factors is 293.

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 = 188880333954/(1x293)

LCM = 188880333954/293

LCM = 644642778

Thus, we can understand that the LCM of 871,879,586,421 is 644642778.
