Given numbers are 855,388,684,552

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

The LCM of 855,388,684,552 is 15260040.

Find LCM of 855,388,684,552 with Prime Factorization

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

2 x 2 x 3 x 3 x 19 x 5 x 97 x 1 x 46 = 15260040

Therefore, the lowest common multiple of 855,388,684,552 is 15260040.

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.

855 x 388 x 684 x 552 = 125254408320

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.

855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855

388 : 1, 2, 4, 97, 194, 388

684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684

552 : 1, 2, 3, 4, 6, 8, 12, 23, 24, 46, 69, 92, 138, 184, 276, 552

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 855,388,684,552, is 1.

Now, the common factors can be found like this.

855:3x 3x 5x 19

388:2x 2x 97

684:2x 2x 3x 3x 19

552:2x 2x 2x 3x 23

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 2x 3x 3x 3x 19 = 8208

Therefore, the value for common factors is 8208.

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 = 125254408320/(1x8208)

LCM = 125254408320/8208

LCM = 15260040

Thus, we can understand that the LCM of 855,388,684,552 is 15260040.
