Given numbers are 330,629,285,209,648
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 330,629,285,209,648 is 425933640.
Find LCM of 330,629,285,209,648 with Prime Factorization
| 2 | 330, 629, 285, 209, 648 |
| 3 | 165, 629, 285, 209, 324 |
| 5 | 55, 629, 95, 209, 108 |
| 11 | 11, 629, 19, 209, 108 |
| 19 | 1, 629, 19, 19, 108 |
| 1, 629, 1, 1, 108 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 11 x 19 x 1 x 629 x 1 x 1 x 108 = 425933640
Therefore, the lowest common multiple of 330,629,285,209,648 is 425933640.
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 629 x 285 x 209 x 648 = 8011811768400
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
629 : 1, 17, 37, 629
285 : 1, 3, 5, 15, 19, 57, 95, 285
209 : 1, 11, 19, 209
648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 330,629,285,209,648, is 1.
Now, the common factors can be found like this.
330:2x 3x 5x 11
629:17x 37
285:3x 5x 19
209:11x 19
648:2x 2x 2x 3x 3x 3x 3
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 5x 11x 19 = 18810
Therefore, the value for common factors is 18810.
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 = 8011811768400/(1x18810)
LCM = 8011811768400/18810
LCM = 425933640
Thus, we can understand that the LCM of 330,629,285,209,648 is 425933640.
