Given numbers are 330,183,561
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 330,183,561 is 342210.
Find LCM of 330,183,561 with Prime Factorization
| 3 | 330, 183, 561 |
| 11 | 110, 61, 187 |
| 10, 61, 17 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 10 x 61 x 17 = 342210
Therefore, the lowest common multiple of 330,183,561 is 342210.
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 183 x 561 = 33878790
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
183 : 1, 3, 61, 183
561 : 1, 3, 11, 17, 33, 51, 187, 561
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 330,183,561, is 3.
Now, the common factors can be found like this.
330:2x 3x 5x 11
183:3x 61
561:3x 11x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 11 = 33
Therefore, the value for common factors is 33.
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 = 33878790/(3x33)
LCM = 33878790/99
LCM = 342210
Thus, we can understand that the LCM of 330,183,561 is 342210.
