Find LCM of 834,468,855,494 with Prime Factorization
| 2 | 834, 468, 855, 494 |
| 3 | 417, 234, 855, 247 |
| 3 | 139, 78, 285, 247 |
| 13 | 139, 26, 95, 247 |
| 19 | 139, 2, 95, 19 |
| 139, 2, 5, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 13 x 19 x 139 x 2 x 5 x 1 = 6179940
Therefore, the lowest common multiple of 834,468,855,494 is 6179940.
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.
834 x 468 x 855 x 494 = 164856079440
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.
834 : 1, 2, 3, 6, 139, 278, 417, 834
468 : 1, 2, 3, 4, 6, 9, 12, 13, 18, 26, 36, 39, 52, 78, 117, 156, 234, 468
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
494 : 1, 2, 13, 19, 26, 38, 247, 494
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 834,468,855,494, is 1.
Now, the common factors can be found like this.
834:2x 3x 139
468:2x 2x 3x 3x 13
855:3x 3x 5x 19
494:2x 13x 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 3x 3x 3x 13x 19 = 26676
Therefore, the value for common factors is 26676.
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 = 164856079440/(1x26676)
LCM = 164856079440/26676
LCM = 6179940
Thus, we can understand that the LCM of 834,468,855,494 is 6179940.
