Given numbers are 822,393,687,724,768
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 822,393,687,724,768 is 571303835904.
Find LCM of 822,393,687,724,768 with Prime Factorization
| 2 | 822, 393, 687, 724, 768 |
| 2 | 411, 393, 687, 362, 384 |
| 3 | 411, 393, 687, 181, 192 |
| 137, 131, 229, 181, 64 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 137 x 131 x 229 x 181 x 64 = 571303835904
Therefore, the lowest common multiple of 822,393,687,724,768 is 571303835904.
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.
822 x 393 x 687 x 724 x 768 = 123401628555264
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.
822 : 1, 2, 3, 6, 137, 274, 411, 822
393 : 1, 3, 131, 393
687 : 1, 3, 229, 687
724 : 1, 2, 4, 181, 362, 724
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 822,393,687,724,768, is 1.
Now, the common factors can be found like this.
822:2x 3x 137
393:3x 131
687:3x 229
724:2x 2x 181
768:2x 2x 2x 2x 2x 2x 2x 2x 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 3x 3x 3 = 216
Therefore, the value for common factors is 216.
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 = 123401628555264/(1x216)
LCM = 123401628555264/216
LCM = 571303835904
Thus, we can understand that the LCM of 822,393,687,724,768 is 571303835904.
