The LCM of 885,280,257,560 is 25473840.
Find LCM of 885,280,257,560 with Prime Factorization
| 2 | 885, 280, 257, 560 |
| 2 | 885, 140, 257, 280 |
| 2 | 885, 70, 257, 140 |
| 5 | 885, 35, 257, 70 |
| 7 | 177, 7, 257, 14 |
| 177, 1, 257, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 7 x 177 x 1 x 257 x 2 = 25473840
Therefore, the lowest common multiple of 885,280,257,560 is 25473840.
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.
885 x 280 x 257 x 560 = 35663376000
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.
885 : 1, 3, 5, 15, 59, 177, 295, 885
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
257 : 1, 257
560 : 1, 2, 4, 5, 7, 8, 10, 14, 16, 20, 28, 35, 40, 56, 70, 80, 112, 140, 280, 560
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 885,280,257,560, is 1.
Now, the common factors can be found like this.
885:3x 5x 59
280:2x 2x 2x 5x 7
257:257
560:2x 2x 2x 2x 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 5x 5x 7 = 1400
Therefore, the value for common factors is 1400.
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 = 35663376000/(1x1400)
LCM = 35663376000/1400
LCM = 25473840
Thus, we can understand that the LCM of 885,280,257,560 is 25473840.
