The LCM of 686,917,303,458,147 is 6235532142.
Find LCM of 686,917,303,458,147 with Prime Factorization
| 2 | 686, 917, 303, 458, 147 |
| 3 | 343, 917, 303, 229, 147 |
| 7 | 343, 917, 101, 229, 49 |
| 7 | 7, 131, 101, 229, 49 |
| 1, 131, 101, 229, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 7 x 1 x 131 x 101 x 229 x 7 = 6235532142
Therefore, the lowest common multiple of 686,917,303,458,147 is 6235532142.
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 917 x 303 x 458 x 147 = 12832725148236
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
917 : 1, 7, 131, 917
303 : 1, 3, 101, 303
458 : 1, 2, 229, 458
147 : 1, 3, 7, 21, 49, 147
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 686,917,303,458,147, is 1.
Now, the common factors can be found like this.
686:2x 7x 7x 7
917:7x 131
303:3x 101
458:2x 229
147:3x 7x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 7x 7x 7 = 2058
Therefore, the value for common factors is 2058.
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 = 12832725148236/(1x2058)
LCM = 12832725148236/2058
LCM = 6235532142
Thus, we can understand that the LCM of 686,917,303,458,147 is 6235532142.
