Given numbers are 805,305,976,208
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 805,305,976,208 is 10213840.
Find LCM of 805,305,976,208 with Prime Factorization
| 2 | 805, 305, 976, 208 |
| 2 | 805, 305, 488, 104 |
| 2 | 805, 305, 244, 52 |
| 2 | 805, 305, 122, 26 |
| 5 | 805, 305, 61, 13 |
| 61 | 161, 61, 61, 13 |
| 161, 1, 1, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 5 x 61 x 161 x 1 x 1 x 13 = 10213840
Therefore, the lowest common multiple of 805,305,976,208 is 10213840.
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.
805 x 305 x 976 x 208 = 49843539200
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.
805 : 1, 5, 7, 23, 35, 115, 161, 805
305 : 1, 5, 61, 305
976 : 1, 2, 4, 8, 16, 61, 122, 244, 488, 976
208 : 1, 2, 4, 8, 13, 16, 26, 52, 104, 208
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 805,305,976,208, is 1.
Now, the common factors can be found like this.
805:5x 7x 23
305:5x 61
976:2x 2x 2x 2x 61
208:2x 2x 2x 2x 13
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 2x 5x 61 = 4880
Therefore, the value for common factors is 4880.
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 = 49843539200/(1x4880)
LCM = 49843539200/4880
LCM = 10213840
Thus, we can understand that the LCM of 805,305,976,208 is 10213840.
