Given numbers are 990,206,870,230

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

The LCM of 990,206,870,230 is 68013990.

Find LCM of 990,206,870,230 with Prime Factorization

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

2 x 3 x 5 x 33 x 103 x 29 x 23 = 68013990

Therefore, the lowest common multiple of 990,206,870,230 is 68013990.

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 206 x 870 x 230 = 40808394000

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

206 : 1, 2, 103, 206

870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870

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

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 990,206,870,230, is 2.

Now, the common factors can be found like this.

990:2x 3x 3x 5x 11

206:2x 103

870:2x 3x 5x 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 3x 5x 5 = 300

Therefore, the value for common factors is 300.

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 = 40808394000/(2x300)

LCM = 40808394000/600

LCM = 68013990

Thus, we can understand that the LCM of 990,206,870,230 is 68013990.
