Given numbers are 990,770,258,554

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

The LCM of 990,770,258,554 is 82543230.

Find LCM of 990,770,258,554 with Prime Factorization

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

2 x 3 x 5 x 11 x 3 x 7 x 43 x 277 = 82543230

Therefore, the lowest common multiple of 990,770,258,554 is 82543230.

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.

990 x 770 x 258 x 554 = 108957063600

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.

990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990

770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770

258 : 1, 2, 3, 6, 43, 86, 129, 258

554 : 1, 2, 277, 554

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 990,770,258,554, is 2.

Now, the common factors can be found like this.

990:2x 3x 3x 5x 11

770:2x 5x 7x 11

258:2x 3x 43

554:2x 277

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 3x 5x 11 = 660

Therefore, the value for common factors is 660.

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 = 108957063600/(2x660)

LCM = 108957063600/1320

LCM = 82543230

Thus, we can understand that the LCM of 990,770,258,554 is 82543230.
