The LCM of 345,840,768,482 is 148995840.
Find LCM of 345,840,768,482 with Prime Factorization
| 2 | 345, 840, 768, 482 |
| 2 | 345, 420, 384, 241 |
| 2 | 345, 210, 192, 241 |
| 3 | 345, 105, 96, 241 |
| 5 | 115, 35, 32, 241 |
| 23, 7, 32, 241 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 23 x 7 x 32 x 241 = 148995840
Therefore, the lowest common multiple of 345,840,768,482 is 148995840.
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.
345 x 840 x 768 x 482 = 107277004800
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.
345 : 1, 3, 5, 15, 23, 69, 115, 345
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
482 : 1, 2, 241, 482
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 345,840,768,482, is 1.
Now, the common factors can be found like this.
345:3x 5x 23
840:2x 2x 2x 3x 5x 7
768:2x 2x 2x 2x 2x 2x 2x 2x 3
482:2x 241
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 3x 3x 5 = 720
Therefore, the value for common factors is 720.
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 = 107277004800/(1x720)
LCM = 107277004800/720
LCM = 148995840
Thus, we can understand that the LCM of 345,840,768,482 is 148995840.
