Find LCM of 908,138,645,720,395 with Prime Factorization
| 2 | 908, 138, 645, 720, 395 |
| 2 | 454, 69, 645, 360, 395 |
| 3 | 227, 69, 645, 180, 395 |
| 5 | 227, 23, 215, 60, 395 |
| 227, 23, 43, 12, 79 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 227 x 23 x 43 x 12 x 79 = 12769730640
Therefore, the lowest common multiple of 908,138,645,720,395 is 12769730640.
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.
908 x 138 x 645 x 720 x 395 = 22985515152000
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.
908 : 1, 2, 4, 227, 454, 908
138 : 1, 2, 3, 6, 23, 46, 69, 138
645 : 1, 3, 5, 15, 43, 129, 215, 645
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
395 : 1, 5, 79, 395
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 908,138,645,720,395, is 1.
Now, the common factors can be found like this.
908:2x 2x 227
138:2x 3x 23
645:3x 5x 43
720:2x 2x 2x 2x 3x 3x 5
395:5x 79
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 3x 5x 5 = 1800
Therefore, the value for common factors is 1800.
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 = 22985515152000/(1x1800)
LCM = 22985515152000/1800
LCM = 12769730640
Thus, we can understand that the LCM of 908,138,645,720,395 is 12769730640.
