Given numbers are 550,235,620,990

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

The LCM of 550,235,620,990 is 14424300.

Find LCM of 550,235,620,990 with Prime Factorization

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

2 x 5 x 11 x 5 x 47 x 62 x 9 = 14424300

Therefore, the lowest common multiple of 550,235,620,990 is 14424300.

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.

550 x 235 x 620 x 990 = 79333650000

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.

550 : 1, 2, 5, 10, 11, 22, 25, 50, 55, 110, 275, 550

235 : 1, 5, 47, 235

620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620

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

5 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 550,235,620,990, is 5.

Now, the common factors can be found like this.

550:2x 5x 5x 11

235:5x 47

620:2x 2x 5x 31

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 = 79333650000/(5x1100)

LCM = 79333650000/5500

LCM = 14424300

Thus, we can understand that the LCM of 550,235,620,990 is 14424300.
