Given numbers are 350,440,446,990

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

The LCM of 350,440,446,990 is 30907800.

Find LCM of 350,440,446,990 with Prime Factorization

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

2 x 5 x 11 x 35 x 4 x 223 x 9 = 30907800

Therefore, the lowest common multiple of 350,440,446,990 is 30907800.

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.

350 x 440 x 446 x 990 = 67997160000

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.

350 : 1, 2, 5, 7, 10, 14, 25, 35, 50, 70, 175, 350

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

446 : 1, 2, 223, 446

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 350,440,446,990, is 2.

Now, the common factors can be found like this.

350:2x 5x 5x 7

440:2x 2x 2x 5x 11

446:2x 223

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 5x 5x 11 = 1100

Therefore, the value for common factors is 1100.

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 = 67997160000/(2x1100)

LCM = 67997160000/2200

LCM = 30907800

Thus, we can understand that the LCM of 350,440,446,990 is 30907800.
