Given numbers are 686,903,899,660,450
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 686,903,899,660,450 is 131267574900.
Find LCM of 686,903,899,660,450 with Prime Factorization
| 2 | 686, 903, 899, 660, 450 |
| 3 | 343, 903, 899, 330, 225 |
| 5 | 343, 301, 899, 110, 75 |
| 7 | 343, 301, 899, 22, 15 |
| 49, 43, 899, 22, 15 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 49 x 43 x 899 x 22 x 15 = 131267574900
Therefore, the lowest common multiple of 686,903,899,660,450 is 131267574900.
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.
686 x 903 x 899 x 660 x 450 = 165397144374000
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.
686 : 1, 2, 7, 14, 49, 98, 343, 686
903 : 1, 3, 7, 21, 43, 129, 301, 903
899 : 1, 29, 31, 899
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
450 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 25, 30, 45, 50, 75, 90, 150, 225, 450
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 686,903,899,660,450, is 1.
Now, the common factors can be found like this.
686:2x 7x 7x 7
903:3x 7x 43
899:29x 31
660:2x 2x 3x 5x 11
450:2x 3x 3x 5x 5
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 7 = 1260
Therefore, the value for common factors is 1260.
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 = 165397144374000/(1x1260)
LCM = 165397144374000/1260
LCM = 131267574900
Thus, we can understand that the LCM of 686,903,899,660,450 is 131267574900.
