Given numbers are 768,324,342,796
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 768,324,342,796 is 78402816.
Find LCM of 768,324,342,796 with Prime Factorization
| 2 | 768, 324, 342, 796 |
| 2 | 384, 162, 171, 398 |
| 3 | 192, 81, 171, 199 |
| 3 | 64, 27, 57, 199 |
| 64, 9, 19, 199 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 64 x 9 x 19 x 199 = 78402816
Therefore, the lowest common multiple of 768,324,342,796 is 78402816.
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.
768 x 324 x 342 x 796 = 67740033024
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.
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
324 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 324
342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342
796 : 1, 2, 4, 199, 398, 796
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 768,324,342,796, is 2.
Now, the common factors can be found like this.
768:2x 2x 2x 2x 2x 2x 2x 2x 3
324:2x 2x 3x 3x 3x 3
342:2x 3x 3x 19
796:2x 2x 199
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 3 = 432
Therefore, the value for common factors is 432.
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 = 67740033024/(2x432)
LCM = 67740033024/864
LCM = 78402816
Thus, we can understand that the LCM of 768,324,342,796 is 78402816.
