Given numbers are 230,715,195,891,455
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 230,715,195,891,455 is 18648630.
Find LCM of 230,715,195,891,455 with Prime Factorization
| 3 | 230, 715, 195, 891, 455 |
| 5 | 230, 715, 65, 297, 455 |
| 11 | 46, 143, 13, 297, 91 |
| 13 | 46, 13, 13, 27, 91 |
| 46, 1, 1, 27, 7 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 11 x 13 x 46 x 1 x 1 x 27 x 7 = 18648630
Therefore, the lowest common multiple of 230,715,195,891,455 is 18648630.
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.
230 x 715 x 195 x 891 x 455 = 13000426188750
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.
230 : 1, 2, 5, 10, 23, 46, 115, 230
715 : 1, 5, 11, 13, 55, 65, 143, 715
195 : 1, 3, 5, 13, 15, 39, 65, 195
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
455 : 1, 5, 7, 13, 35, 65, 91, 455
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 230,715,195,891,455, is 1.
Now, the common factors can be found like this.
230:2x 5x 23
715:5x 11x 13
195:3x 5x 13
891:3x 3x 3x 3x 11
455:5x 7x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 5x 5x 11x 13x 13 = 697125
Therefore, the value for common factors is 697125.
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 = 13000426188750/(1x697125)
LCM = 13000426188750/697125
LCM = 18648630
Thus, we can understand that the LCM of 230,715,195,891,455 is 18648630.
