Given numbers are 190,412,440,230,990

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

The LCM of 190,412,440,230,990 is 178243560.

Find LCM of 190,412,440,230,990 with Prime Factorization

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

2 x 2 x 5 x 11 x 19 x 103 x 2 x 23 x 9 = 178243560

Therefore, the lowest common multiple of 190,412,440,230,990 is 178243560.

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.

190 x 412 x 440 x 230 x 990 = 7842716640000

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.

190 : 1, 2, 5, 10, 19, 38, 95, 190

412 : 1, 2, 4, 103, 206, 412

440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440

230 : 1, 2, 5, 10, 23, 46, 115, 230

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

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 190,412,440,230,990, is 2.

Now, the common factors can be found like this.

190:2x 5x 19

412:2x 2x 103

440:2x 2x 2x 5x 11

230:2x 5x 23

990:2x 3x 3x 5x 11

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 5x 5x 5x 11 = 22000

Therefore, the value for common factors is 22000.

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 = 7842716640000/(2x22000)

LCM = 7842716640000/44000

LCM = 178243560

Thus, we can understand that the LCM of 190,412,440,230,990 is 178243560.
