Given numbers are 842,470,391,879

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

The LCM of 842,470,391,879 is 68005742430.

Find LCM of 842,470,391,879 with Prime Factorization

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

2 x 421 x 235 x 391 x 879 = 68005742430

Therefore, the lowest common multiple of 842,470,391,879 is 68005742430.

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.

842 x 470 x 391 x 879 = 136011484860

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.

842 : 1, 2, 421, 842

470 : 1, 2, 5, 10, 47, 94, 235, 470

391 : 1, 17, 23, 391

879 : 1, 3, 293, 879

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 842,470,391,879, is 1.

Now, the common factors can be found like this.

842:2x 421

470:2x 5x 47

391:17x 23

879:3x 293

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

2 = 2

Therefore, the value for common factors is 2.

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 = 136011484860/(1x2)

LCM = 136011484860/2

LCM = 68005742430

Thus, we can understand that the LCM of 842,470,391,879 is 68005742430.
