Find LCM of 209,408,788,442,330 with Prime Factorization
| 2 | 209, 408, 788, 442, 330 |
| 2 | 209, 204, 394, 221, 165 |
| 3 | 209, 102, 197, 221, 165 |
| 11 | 209, 34, 197, 221, 55 |
| 17 | 19, 34, 197, 221, 5 |
| 19, 2, 197, 13, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 11 x 17 x 19 x 2 x 197 x 13 x 5 = 1091907960
Therefore, the lowest common multiple of 209,408,788,442,330 is 1091907960.
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 408 x 788 x 442 x 330 = 9800965848960
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
408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408
788 : 1, 2, 4, 197, 394, 788
442 : 1, 2, 13, 17, 26, 34, 221, 442
330 : 1, 2, 3, 5, 6, 10, 11, 15, 22, 30, 33, 55, 66, 110, 165, 330
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 209,408,788,442,330, is 1.
Now, the common factors can be found like this.
209:11x 19
408:2x 2x 2x 3x 17
788:2x 2x 197
442:2x 13x 17
330:2x 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 2x 2x 3x 11x 17 = 8976
Therefore, the value for common factors is 8976.
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 = 9800965848960/(1x8976)
LCM = 9800965848960/8976
LCM = 1091907960
Thus, we can understand that the LCM of 209,408,788,442,330 is 1091907960.
