Find LCM of 105,808,442,755,816 with Prime Factorization
| 2 | 105, 808, 442, 755, 816 |
| 2 | 105, 404, 221, 755, 408 |
| 2 | 105, 202, 221, 755, 204 |
| 3 | 105, 101, 221, 755, 102 |
| 5 | 35, 101, 221, 755, 34 |
| 17 | 7, 101, 221, 151, 34 |
| 7, 101, 13, 151, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 17 x 7 x 101 x 13 x 151 x 2 = 5662391280
Therefore, the lowest common multiple of 105,808,442,755,816 is 5662391280.
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.
105 x 808 x 442 x 755 x 816 = 23102556422400
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.
105 : 1, 3, 5, 7, 15, 21, 35, 105
808 : 1, 2, 4, 8, 101, 202, 404, 808
442 : 1, 2, 13, 17, 26, 34, 221, 442
755 : 1, 5, 151, 755
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 105,808,442,755,816, is 1.
Now, the common factors can be found like this.
105:3x 5x 7
808:2x 2x 2x 101
442:2x 13x 17
755:5x 151
816:2x 2x 2x 2x 3x 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 2x 3x 5x 17 = 4080
Therefore, the value for common factors is 4080.
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 = 23102556422400/(1x4080)
LCM = 23102556422400/4080
LCM = 5662391280
Thus, we can understand that the LCM of 105,808,442,755,816 is 5662391280.
