Given numbers are 209,330,998,811
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 209,330,998,811 is 2537400030.
Find LCM of 209,330,998,811 with Prime Factorization
| 2 | 209, 330, 998, 811 |
| 11 | 209, 165, 499, 811 |
| 19, 15, 499, 811 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 19 x 15 x 499 x 811 = 2537400030
Therefore, the lowest common multiple of 209,330,998,811 is 2537400030.
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.
209 x 330 x 998 x 811 = 55822800660
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.
209 : 1, 11, 19, 209
330 : 1, 2, 3, 5, 6, 10, 11, 15, 22, 30, 33, 55, 66, 110, 165, 330
998 : 1, 2, 499, 998
811 : 1, 811
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 209,330,998,811, is 1.
Now, the common factors can be found like this.
209:11x 19
330:2x 3x 5x 11
998:2x 499
811:811
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11 = 22
Therefore, the value for common factors is 22.
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 = 55822800660/(1x22)
LCM = 55822800660/22
LCM = 2537400030
Thus, we can understand that the LCM of 209,330,998,811 is 2537400030.
