Given numbers are 809,261,957,781,664
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 809,261,957,781,664 is 109498493016.
Find LCM of 809,261,957,781,664 with Prime Factorization
| 3 | 809, 261, 957, 781, 664 |
| 11 | 809, 87, 319, 781, 664 |
| 29 | 809, 87, 29, 71, 664 |
| 809, 3, 1, 71, 664 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 29 x 809 x 3 x 1 x 71 x 664 = 109498493016
Therefore, the lowest common multiple of 809,261,957,781,664 is 109498493016.
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.
809 x 261 x 957 x 781 x 664 = 104790057816312
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.
809 : 1, 809
261 : 1, 3, 9, 29, 87, 261
957 : 1, 3, 11, 29, 33, 87, 319, 957
781 : 1, 11, 71, 781
664 : 1, 2, 4, 8, 83, 166, 332, 664
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 809,261,957,781,664, is 1.
Now, the common factors can be found like this.
809:809
261:3x 3x 29
957:3x 11x 29
781:11x 71
664:2x 2x 2x 83
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 11x 29 = 957
Therefore, the value for common factors is 957.
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 = 104790057816312/(1x957)
LCM = 104790057816312/957
LCM = 109498493016
Thus, we can understand that the LCM of 809,261,957,781,664 is 109498493016.
