Given numbers are 768,846,756,452
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 768,846,756,452 is 256967424.
Find LCM of 768,846,756,452 with Prime Factorization
| 2 | 768, 846, 756, 452 |
| 2 | 384, 423, 378, 226 |
| 3 | 192, 423, 189, 113 |
| 3 | 64, 141, 63, 113 |
| 64, 47, 21, 113 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 64 x 47 x 21 x 113 = 256967424
Therefore, the lowest common multiple of 768,846,756,452 is 256967424.
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 846 x 756 x 452 = 222019854336
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
846 : 1, 2, 3, 6, 9, 18, 47, 94, 141, 282, 423, 846
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
452 : 1, 2, 4, 113, 226, 452
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 768,846,756,452, is 2.
Now, the common factors can be found like this.
768:2x 2x 2x 2x 2x 2x 2x 2x 3
846:2x 3x 3x 47
756:2x 2x 3x 3x 3x 7
452:2x 2x 113
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 = 222019854336/(2x432)
LCM = 222019854336/864
LCM = 256967424
Thus, we can understand that the LCM of 768,846,756,452 is 256967424.
