Given numbers are 117,908,687,908,689
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 117,908,687,908,689 is 1289386332.
Find LCM of 117,908,687,908,689 with Prime Factorization
| 2 | 117, 908, 687, 908, 689 |
| 2 | 117, 454, 687, 454, 689 |
| 3 | 117, 227, 687, 227, 689 |
| 13 | 39, 227, 229, 227, 689 |
| 227 | 3, 227, 229, 227, 53 |
| 3, 1, 229, 1, 53 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 13 x 227 x 3 x 1 x 229 x 1 x 53 = 1289386332
Therefore, the lowest common multiple of 117,908,687,908,689 is 1289386332.
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.
117 x 908 x 687 x 908 x 689 = 45659748788784
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.
117 : 1, 3, 9, 13, 39, 117
908 : 1, 2, 4, 227, 454, 908
687 : 1, 3, 229, 687
908 : 1, 2, 4, 227, 454, 908
689 : 1, 13, 53, 689
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 117,908,687,908,689, is 1.
Now, the common factors can be found like this.
117:3x 3x 13
908:2x 2x 227
687:3x 229
908:2x 2x 227
689:13x 53
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 3x 13x 227 = 35412
Therefore, the value for common factors is 35412.
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 = 45659748788784/(1x35412)
LCM = 45659748788784/35412
LCM = 1289386332
Thus, we can understand that the LCM of 117,908,687,908,689 is 1289386332.
