The LCM of 898,738,861,747 is 192521322.
Find LCM of 898,738,861,747 with Prime Factorization
| 2 | 898, 738, 861, 747 |
| 3 | 449, 369, 861, 747 |
| 3 | 449, 123, 287, 249 |
| 41 | 449, 41, 287, 83 |
| 449, 1, 7, 83 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 41 x 449 x 1 x 7 x 83 = 192521322
Therefore, the lowest common multiple of 898,738,861,747 is 192521322.
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.
898 x 738 x 861 x 747 = 426242206908
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.
898 : 1, 2, 449, 898
738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738
861 : 1, 3, 7, 21, 41, 123, 287, 861
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 898,738,861,747, is 1.
Now, the common factors can be found like this.
898:2x 449
738:2x 3x 3x 41
861:3x 7x 41
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 3x 3x 3x 41 = 2214
Therefore, the value for common factors is 2214.
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 = 426242206908/(1x2214)
LCM = 426242206908/2214
LCM = 192521322
Thus, we can understand that the LCM of 898,738,861,747 is 192521322.
