The LCM of 328,915,788,888,999 is 19688172120.
Find LCM of 328,915,788,888,999 with Prime Factorization
| 2 | 328, 915, 788, 888, 999 |
| 2 | 164, 915, 394, 444, 999 |
| 2 | 82, 915, 197, 222, 999 |
| 3 | 41, 915, 197, 111, 999 |
| 37 | 41, 305, 197, 37, 333 |
| 41, 305, 197, 1, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 37 x 41 x 305 x 197 x 1 x 9 = 19688172120
Therefore, the lowest common multiple of 328,915,788,888,999 is 19688172120.
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.
328 x 915 x 788 x 888 x 999 = 209797162110720
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.
328 : 1, 2, 4, 8, 41, 82, 164, 328
915 : 1, 3, 5, 15, 61, 183, 305, 915
788 : 1, 2, 4, 197, 394, 788
888 : 1, 2, 3, 4, 6, 8, 12, 24, 37, 74, 111, 148, 222, 296, 444, 888
999 : 1, 3, 9, 27, 37, 111, 333, 999
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 328,915,788,888,999, is 1.
Now, the common factors can be found like this.
328:2x 2x 2x 41
915:3x 5x 61
788:2x 2x 197
888:2x 2x 2x 3x 37
999:3x 3x 3x 37
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 2x 3x 3x 37 = 10656
Therefore, the value for common factors is 10656.
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 = 209797162110720/(1x10656)
LCM = 209797162110720/10656
LCM = 19688172120
Thus, we can understand that the LCM of 328,915,788,888,999 is 19688172120.
