Given numbers are 330,326,387,326,638
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 330,326,387,326,638 is 201228390.
Find LCM of 330,326,387,326,638 with Prime Factorization
| 2 | 330, 326, 387, 326, 638 |
| 3 | 165, 163, 387, 163, 319 |
| 11 | 55, 163, 129, 163, 319 |
| 163 | 5, 163, 129, 163, 29 |
| 5, 1, 129, 1, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 163 x 5 x 1 x 129 x 1 x 29 = 201228390
Therefore, the lowest common multiple of 330,326,387,326,638 is 201228390.
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 326 x 387 x 326 x 638 = 8659260078480
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
326 : 1, 2, 163, 326
387 : 1, 3, 9, 43, 129, 387
326 : 1, 2, 163, 326
638 : 1, 2, 11, 22, 29, 58, 319, 638
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 330,326,387,326,638, is 1.
Now, the common factors can be found like this.
330:2x 3x 5x 11
326:2x 163
387:3x 3x 43
326:2x 163
638:2x 11x 29
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 3x 11x 163 = 43032
Therefore, the value for common factors is 43032.
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 = 8659260078480/(1x43032)
LCM = 8659260078480/43032
LCM = 201228390
Thus, we can understand that the LCM of 330,326,387,326,638 is 201228390.
