Given numbers are 990,509,812,230

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

The LCM of 990,509,812,230 is 4705511580.

Find LCM of 990,509,812,230 with Prime Factorization

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

2 x 5 x 99 x 509 x 406 x 23 = 4705511580

Therefore, the lowest common multiple of 990,509,812,230 is 4705511580.

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 509 x 812 x 230 = 94110231600

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

509 : 1, 509

812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 990,509,812,230, is 1.

Now, the common factors can be found like this.

990:2x 3x 3x 5x 11

509:509

812:2x 2x 7x 29

230:2x 5x 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 5 = 20

Therefore, the value for common factors is 20.

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 = 94110231600/(1x20)

LCM = 94110231600/20

LCM = 4705511580

Thus, we can understand that the LCM of 990,509,812,230 is 4705511580.
