Find LCM of 904,198,371,645,819 with Prime Factorization
| 2 | 904, 198, 371, 645, 819 |
| 3 | 452, 99, 371, 645, 819 |
| 3 | 452, 33, 371, 215, 273 |
| 7 | 452, 11, 371, 215, 91 |
| 452, 11, 53, 215, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 7 x 452 x 11 x 53 x 215 x 13 = 92802429720
Therefore, the lowest common multiple of 904,198,371,645,819 is 92802429720.
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.
904 x 198 x 371 x 645 x 819 = 35079318434160
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.
904 : 1, 2, 4, 8, 113, 226, 452, 904
198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198
371 : 1, 7, 53, 371
645 : 1, 3, 5, 15, 43, 129, 215, 645
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 904,198,371,645,819, is 1.
Now, the common factors can be found like this.
904:2x 2x 2x 113
198:2x 3x 3x 11
371:7x 53
645:3x 5x 43
819:3x 3x 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.
2x 3x 3x 3x 7 = 378
Therefore, the value for common factors is 378.
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 = 35079318434160/(1x378)
LCM = 35079318434160/378
LCM = 92802429720
Thus, we can understand that the LCM of 904,198,371,645,819 is 92802429720.
