The LCM of 330,494,209,220 is 163020.
Find LCM of 330,494,209,220 with Prime Factorization
| 2 | 330, 494, 209, 220 |
| 5 | 165, 247, 209, 110 |
| 11 | 33, 247, 209, 22 |
| 19 | 3, 247, 19, 2 |
| 3, 13, 1, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 11 x 19 x 3 x 13 x 1 x 2 = 163020
Therefore, the lowest common multiple of 330,494,209,220 is 163020.
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.
330 x 494 x 209 x 220 = 7495659600
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.
330 : 1, 2, 3, 5, 6, 10, 11, 15, 22, 30, 33, 55, 66, 110, 165, 330
494 : 1, 2, 13, 19, 26, 38, 247, 494
209 : 1, 11, 19, 209
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 330,494,209,220, is 1.
Now, the common factors can be found like this.
330:2x 3x 5x 11
494:2x 13x 19
209:11x 19
220:2x 2x 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 11x 11x 19 = 45980
Therefore, the value for common factors is 45980.
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 = 7495659600/(1x45980)
LCM = 7495659600/45980
LCM = 163020
Thus, we can understand that the LCM of 330,494,209,220 is 163020.
