Find LCM of 928,645,384,288 with Prime Factorization
| 2 | 928, 645, 384, 288 |
| 2 | 464, 645, 192, 144 |
| 2 | 232, 645, 96, 72 |
| 2 | 116, 645, 48, 36 |
| 2 | 58, 645, 24, 18 |
| 3 | 29, 645, 12, 9 |
| 29, 215, 4, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 3 x 29 x 215 x 4 x 3 = 7182720
Therefore, the lowest common multiple of 928,645,384,288 is 7182720.
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.
928 x 645 x 384 x 288 = 66195947520
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.
928 : 1, 2, 4, 8, 16, 29, 32, 58, 116, 232, 464, 928
645 : 1, 3, 5, 15, 43, 129, 215, 645
384 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 384
288 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 72, 96, 144, 288
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 928,645,384,288, is 1.
Now, the common factors can be found like this.
928:2x 2x 2x 2x 2x 29
645:3x 5x 43
384:2x 2x 2x 2x 2x 2x 2x 3
288:2x 2x 2x 2x 2x 3x 3
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 2x 2x 2x 2x 2x 3x 3 = 9216
Therefore, the value for common factors is 9216.
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 = 66195947520/(1x9216)
LCM = 66195947520/9216
LCM = 7182720
Thus, we can understand that the LCM of 928,645,384,288 is 7182720.
