The LCM of 423,813,696,738,638 is 11994280056.
Find LCM of 423,813,696,738,638 with Prime Factorization
| 2 | 423, 813, 696, 738, 638 |
| 3 | 423, 813, 348, 369, 319 |
| 3 | 141, 271, 116, 123, 319 |
| 29 | 47, 271, 116, 41, 319 |
| 47, 271, 4, 41, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 29 x 47 x 271 x 4 x 41 x 11 = 11994280056
Therefore, the lowest common multiple of 423,813,696,738,638 is 11994280056.
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.
423 x 813 x 696 x 738 x 638 = 112698255406176
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.
423 : 1, 3, 9, 47, 141, 423
813 : 1, 3, 271, 813
696 : 1, 2, 3, 4, 6, 8, 12, 24, 29, 58, 87, 116, 174, 232, 348, 696
738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738
638 : 1, 2, 11, 22, 29, 58, 319, 638
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 423,813,696,738,638, is 1.
Now, the common factors can be found like this.
423:3x 3x 47
813:3x 271
696:2x 2x 2x 3x 29
738:2x 3x 3x 41
638:2x 11x 29
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 29 = 9396
Therefore, the value for common factors is 9396.
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 = 112698255406176/(1x9396)
LCM = 112698255406176/9396
LCM = 11994280056
Thus, we can understand that the LCM of 423,813,696,738,638 is 11994280056.
