Given numbers are 330,664,381,581
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 330,664,381,581 is 97398840.
Find LCM of 330,664,381,581 with Prime Factorization
| 2 | 330, 664, 381, 581 |
| 3 | 165, 332, 381, 581 |
| 83 | 55, 332, 127, 581 |
| 55, 4, 127, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 83 x 55 x 4 x 127 x 7 = 97398840
Therefore, the lowest common multiple of 330,664,381,581 is 97398840.
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 664 x 381 x 581 = 48504622320
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
664 : 1, 2, 4, 8, 83, 166, 332, 664
381 : 1, 3, 127, 381
581 : 1, 7, 83, 581
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 330,664,381,581, is 1.
Now, the common factors can be found like this.
330:2x 3x 5x 11
664:2x 2x 2x 83
381:3x 127
581:7x 83
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 83 = 498
Therefore, the value for common factors is 498.
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 = 48504622320/(1x498)
LCM = 48504622320/498
LCM = 97398840
Thus, we can understand that the LCM of 330,664,381,581 is 97398840.
