Find LCM of 813,395,848,342,945 with Prime Factorization
| 2 | 813, 395, 848, 342, 945 |
| 3 | 813, 395, 424, 171, 945 |
| 3 | 271, 395, 424, 57, 315 |
| 5 | 271, 395, 424, 19, 105 |
| 271, 79, 424, 19, 21 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 271 x 79 x 424 x 19 x 21 = 325970008560
Therefore, the lowest common multiple of 813,395,848,342,945 is 325970008560.
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.
813 x 395 x 848 x 342 x 945 = 88011902311200
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.
813 : 1, 3, 271, 813
395 : 1, 5, 79, 395
848 : 1, 2, 4, 8, 16, 53, 106, 212, 424, 848
342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 813,395,848,342,945, is 1.
Now, the common factors can be found like this.
813:3x 271
395:5x 79
848:2x 2x 2x 2x 53
342:2x 3x 3x 19
945:3x 3x 3x 5x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3x 5 = 270
Therefore, the value for common factors is 270.
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 = 88011902311200/(1x270)
LCM = 88011902311200/270
LCM = 325970008560
Thus, we can understand that the LCM of 813,395,848,342,945 is 325970008560.
