Find LCM of 308,760,808,665,393 with Prime Factorization
| 2 | 308, 760, 808, 665, 393 |
| 2 | 154, 380, 404, 665, 393 |
| 2 | 77, 190, 202, 665, 393 |
| 5 | 77, 95, 101, 665, 393 |
| 7 | 77, 19, 101, 133, 393 |
| 19 | 11, 19, 101, 19, 393 |
| 11, 1, 101, 1, 393 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 7 x 19 x 11 x 1 x 101 x 1 x 393 = 2322834360
Therefore, the lowest common multiple of 308,760,808,665,393 is 2322834360.
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.
308 x 760 x 808 x 665 x 393 = 49429915180800
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.
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
760 : 1, 2, 4, 5, 8, 10, 19, 20, 38, 40, 76, 95, 152, 190, 380, 760
808 : 1, 2, 4, 8, 101, 202, 404, 808
665 : 1, 5, 7, 19, 35, 95, 133, 665
393 : 1, 3, 131, 393
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 308,760,808,665,393, is 1.
Now, the common factors can be found like this.
308:2x 2x 7x 11
760:2x 2x 2x 5x 19
808:2x 2x 2x 101
665:5x 7x 19
393:3x 131
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 2x 5x 7x 19 = 21280
Therefore, the value for common factors is 21280.
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 = 49429915180800/(1x21280)
LCM = 49429915180800/21280
LCM = 2322834360
Thus, we can understand that the LCM of 308,760,808,665,393 is 2322834360.
