Find LCM of 828,366,324,876,642 with Prime Factorization
| 2 | 828, 366, 324, 876, 642 |
| 2 | 414, 183, 162, 438, 321 |
| 3 | 207, 183, 81, 219, 321 |
| 3 | 69, 61, 27, 73, 107 |
| 23, 61, 9, 73, 107 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 23 x 61 x 9 x 73 x 107 = 3550661892
Therefore, the lowest common multiple of 828,366,324,876,642 is 3550661892.
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.
828 x 366 x 324 x 876 x 642 = 55219893744384
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.
828 : 1, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828
366 : 1, 2, 3, 6, 61, 122, 183, 366
324 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 324
876 : 1, 2, 3, 4, 6, 12, 73, 146, 219, 292, 438, 876
642 : 1, 2, 3, 6, 107, 214, 321, 642
6 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 828,366,324,876,642, is 6.
Now, the common factors can be found like this.
828:2x 2x 3x 3x 23
366:2x 3x 61
324:2x 2x 3x 3x 3x 3
876:2x 2x 3x 73
642:2x 3x 107
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 3x 3 = 2592
Therefore, the value for common factors is 2592.
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 = 55219893744384/(6x2592)
LCM = 55219893744384/15552
LCM = 3550661892
Thus, we can understand that the LCM of 828,366,324,876,642 is 3550661892.
