The LCM of 488,259,280,840 is 1895880.
Find LCM of 488,259,280,840 with Prime Factorization
| 2 | 488, 259, 280, 840 |
| 2 | 244, 259, 140, 420 |
| 2 | 122, 259, 70, 210 |
| 5 | 61, 259, 35, 105 |
| 7 | 61, 259, 7, 21 |
| 61, 37, 1, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 7 x 61 x 37 x 1 x 3 = 1895880
Therefore, the lowest common multiple of 488,259,280,840 is 1895880.
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.
488 x 259 x 280 x 840 = 29727398400
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.
488 : 1, 2, 4, 8, 61, 122, 244, 488
259 : 1, 7, 37, 259
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
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
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 488,259,280,840, is 1.
Now, the common factors can be found like this.
488:2x 2x 2x 61
259:7x 37
280:2x 2x 2x 5x 7
840:2x 2x 2x 3x 5x 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 2x 2x 2x 2x 2x 5x 7x 7 = 15680
Therefore, the value for common factors is 15680.
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 = 29727398400/(1x15680)
LCM = 29727398400/15680
LCM = 1895880
Thus, we can understand that the LCM of 488,259,280,840 is 1895880.
