Find LCM of 898,840,605,471,721 with Prime Factorization
| 2 | 898, 840, 605, 471, 721 |
| 3 | 449, 420, 605, 471, 721 |
| 5 | 449, 140, 605, 157, 721 |
| 7 | 449, 28, 121, 157, 721 |
| 449, 4, 121, 157, 103 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 449 x 4 x 121 x 157 x 103 = 737985577560
Therefore, the lowest common multiple of 898,840,605,471,721 is 737985577560.
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 840 x 605 x 471 x 721 = 154976971287600
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
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
605 : 1, 5, 11, 55, 121, 605
471 : 1, 3, 157, 471
721 : 1, 7, 103, 721
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 898,840,605,471,721, is 1.
Now, the common factors can be found like this.
898:2x 449
840:2x 2x 2x 3x 5x 7
605:5x 11x 11
471:3x 157
721:7x 103
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 5x 7 = 210
Therefore, the value for common factors is 210.
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 = 154976971287600/(1x210)
LCM = 154976971287600/210
LCM = 737985577560
Thus, we can understand that the LCM of 898,840,605,471,721 is 737985577560.
