Given numbers are 556,394,470,278,642

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

The LCM of 556,394,470,278,642 is 8262546420.

Find LCM of 556,394,470,278,642 with Prime Factorization

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

2 x 139 x 2 x 197 x 235 x 1 x 321 = 8262546420

Therefore, the lowest common multiple of 556,394,470,278,642 is 8262546420.

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.

556 x 394 x 470 x 278 x 642 = 18375903238080

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.

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

394 : 1, 2, 197, 394

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

278 : 1, 2, 139, 278

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

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 556,394,470,278,642, is 2.

Now, the common factors can be found like this.

556:2x 2x 139

394:2x 197

470:2x 5x 47

278:2x 139

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 2x 2x 139 = 1112

Therefore, the value for common factors is 1112.

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 = 18375903238080/(2x1112)

LCM = 18375903238080/2224

LCM = 8262546420

Thus, we can understand that the LCM of 556,394,470,278,642 is 8262546420.
