Given numbers are 898,345,646,720,825
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 898,345,646,720,825 is 132090591600.
Find LCM of 898,345,646,720,825 with Prime Factorization
| 2 | 898, 345, 646, 720, 825 |
| 3 | 449, 345, 323, 360, 825 |
| 5 | 449, 115, 323, 120, 275 |
| 449, 23, 323, 24, 55 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 449 x 23 x 323 x 24 x 55 = 132090591600
Therefore, the lowest common multiple of 898,345,646,720,825 is 132090591600.
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 345 x 646 x 720 x 825 = 118881532440000
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
345 : 1, 3, 5, 15, 23, 69, 115, 345
646 : 1, 2, 17, 19, 34, 38, 323, 646
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
825 : 1, 3, 5, 11, 15, 25, 33, 55, 75, 165, 275, 825
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 898,345,646,720,825, is 1.
Now, the common factors can be found like this.
898:2x 449
345:3x 5x 23
646:2x 17x 19
720:2x 2x 2x 2x 3x 3x 5
825:3x 5x 5x 11
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 5x 5 = 900
Therefore, the value for common factors is 900.
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 = 118881532440000/(1x900)
LCM = 118881532440000/900
LCM = 132090591600
Thus, we can understand that the LCM of 898,345,646,720,825 is 132090591600.
