Given numbers are 806,120,685,205,702
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 806,120,685,205,702 is 2444743080.
Find LCM of 806,120,685,205,702 with Prime Factorization
| 2 | 806, 120, 685, 205, 702 |
| 3 | 403, 60, 685, 205, 351 |
| 5 | 403, 20, 685, 205, 117 |
| 13 | 403, 4, 137, 41, 117 |
| 31, 4, 137, 41, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 13 x 31 x 4 x 137 x 41 x 9 = 2444743080
Therefore, the lowest common multiple of 806,120,685,205,702 is 2444743080.
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.
806 x 120 x 685 x 205 x 702 = 9534498012000
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.
806 : 1, 2, 13, 26, 31, 62, 403, 806
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
685 : 1, 5, 137, 685
205 : 1, 5, 41, 205
702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 806,120,685,205,702, is 1.
Now, the common factors can be found like this.
806:2x 13x 31
120:2x 2x 2x 3x 5
685:5x 137
205:5x 41
702:2x 3x 3x 3x 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 3x 5x 5x 13 = 3900
Therefore, the value for common factors is 3900.
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 = 9534498012000/(1x3900)
LCM = 9534498012000/3900
LCM = 2444743080
Thus, we can understand that the LCM of 806,120,685,205,702 is 2444743080.
