Find LCM of 828,309,591,720,684 with Prime Factorization
| 2 | 828, 309, 591, 720, 684 |
| 2 | 414, 309, 591, 360, 342 |
| 3 | 207, 309, 591, 180, 171 |
| 3 | 69, 103, 197, 60, 57 |
| 23, 103, 197, 20, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 23 x 103 x 197 x 20 x 19 = 6384360240
Therefore, the lowest common multiple of 828,309,591,720,684 is 6384360240.
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 309 x 591 x 720 x 684 = 74467177839360
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
309 : 1, 3, 103, 309
591 : 1, 3, 197, 591
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
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 828,309,591,720,684, is 3.
Now, the common factors can be found like this.
828:2x 2x 3x 3x 23
309:3x 103
591:3x 197
720:2x 2x 2x 2x 3x 3x 5
684:2x 2x 3x 3x 19
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 3x 3x 3x 3x 3 = 3888
Therefore, the value for common factors is 3888.
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 = 74467177839360/(3x3888)
LCM = 74467177839360/11664
LCM = 6384360240
Thus, we can understand that the LCM of 828,309,591,720,684 is 6384360240.
