Find LCM of 813,286,702,378 with Prime Factorization
| 2 | 813, 286, 702, 378 |
| 3 | 813, 143, 351, 189 |
| 3 | 271, 143, 117, 63 |
| 3 | 271, 143, 39, 21 |
| 13 | 271, 143, 13, 7 |
| 271, 11, 1, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 13 x 271 x 11 x 1 x 7 = 14648634
Therefore, the lowest common multiple of 813,286,702,378 is 14648634.
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 286 x 702 x 378 = 61700046408
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
286 : 1, 2, 11, 13, 22, 26, 143, 286
702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702
378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 813,286,702,378, is 1.
Now, the common factors can be found like this.
813:3x 271
286:2x 11x 13
702:2x 3x 3x 3x 13
378:2x 3x 3x 3x 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 2x 3x 3x 3x 3x 13 = 4212
Therefore, the value for common factors is 4212.
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 = 61700046408/(1x4212)
LCM = 61700046408/4212
LCM = 14648634
Thus, we can understand that the LCM of 813,286,702,378 is 14648634.
