Given numbers are 183,315,105,255,621
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 183,315,105,255,621 is 22539195.
Find LCM of 183,315,105,255,621 with Prime Factorization
| 3 | 183, 315, 105, 255, 621 |
| 3 | 61, 105, 35, 85, 207 |
| 5 | 61, 35, 35, 85, 69 |
| 7 | 61, 7, 7, 17, 69 |
| 61, 1, 1, 17, 69 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 7 x 61 x 1 x 1 x 17 x 69 = 22539195
Therefore, the lowest common multiple of 183,315,105,255,621 is 22539195.
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.
183 x 315 x 105 x 255 x 621 = 958479267375
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.
183 : 1, 3, 61, 183
315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
105 : 1, 3, 5, 7, 15, 21, 35, 105
255 : 1, 3, 5, 15, 17, 51, 85, 255
621 : 1, 3, 9, 23, 27, 69, 207, 621
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 183,315,105,255,621, is 3.
Now, the common factors can be found like this.
183:3x 61
315:3x 3x 5x 7
105:3x 5x 7
255:3x 5x 17
621:3x 3x 3x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 3x 5x 5x 7 = 14175
Therefore, the value for common factors is 14175.
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 = 958479267375/(3x14175)
LCM = 958479267375/42525
LCM = 22539195
Thus, we can understand that the LCM of 183,315,105,255,621 is 22539195.
