Find LCM of 870,408,988,481,289 with Prime Factorization
| 2 | 870, 408, 988, 481, 289 |
| 2 | 435, 204, 494, 481, 289 |
| 3 | 435, 102, 247, 481, 289 |
| 13 | 145, 34, 247, 481, 289 |
| 17 | 145, 34, 19, 37, 289 |
| 145, 2, 19, 37, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 13 x 17 x 145 x 2 x 19 x 37 x 17 = 9191275080
Therefore, the lowest common multiple of 870,408,988,481,289 is 9191275080.
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.
870 x 408 x 988 x 481 x 289 = 48750523024320
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.
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
481 : 1, 13, 37, 481
289 : 1, 17, 289
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 870,408,988,481,289, is 1.
Now, the common factors can be found like this.
870:2x 3x 5x 29
408:2x 2x 2x 3x 17
988:2x 2x 13x 19
481:13x 37
289:17x 17
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 13x 17 = 5304
Therefore, the value for common factors is 5304.
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 = 48750523024320/(1x5304)
LCM = 48750523024320/5304
LCM = 9191275080
Thus, we can understand that the LCM of 870,408,988,481,289 is 9191275080.
