Find LCM of 813,468,338,724,747 with Prime Factorization
| 2 | 813, 468, 338, 724, 747 |
| 2 | 813, 234, 169, 362, 747 |
| 3 | 813, 117, 169, 181, 747 |
| 3 | 271, 39, 169, 181, 249 |
| 13 | 271, 13, 169, 181, 83 |
| 271, 1, 13, 181, 83 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 13 x 271 x 1 x 13 x 181 x 83 = 24769381572
Therefore, the lowest common multiple of 813,468,338,724,747 is 24769381572.
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 468 x 338 x 724 x 747 = 69552423454176
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
468 : 1, 2, 3, 4, 6, 9, 12, 13, 18, 26, 36, 39, 52, 78, 117, 156, 234, 468
338 : 1, 2, 13, 26, 169, 338
724 : 1, 2, 4, 181, 362, 724
747 : 1, 3, 9, 83, 249, 747
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 813,468,338,724,747, is 1.
Now, the common factors can be found like this.
813:3x 271
468:2x 2x 3x 3x 13
338:2x 13x 13
724:2x 2x 181
747:3x 3x 83
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 3x 3x 3x 13 = 2808
Therefore, the value for common factors is 2808.
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 = 69552423454176/(1x2808)
LCM = 69552423454176/2808
LCM = 24769381572
Thus, we can understand that the LCM of 813,468,338,724,747 is 24769381572.
