Find LCM of 878,660,945,548,857 with Prime Factorization
| 2 | 878, 660, 945, 548, 857 |
| 2 | 439, 330, 945, 274, 857 |
| 3 | 439, 165, 945, 137, 857 |
| 5 | 439, 55, 315, 137, 857 |
| 439, 11, 63, 137, 857 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 439 x 11 x 63 x 137 x 857 = 2143139270580
Therefore, the lowest common multiple of 878,660,945,548,857 is 2143139270580.
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.
878 x 660 x 945 x 548 x 857 = 257176712469600
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.
878 : 1, 2, 439, 878
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
548 : 1, 2, 4, 137, 274, 548
857 : 1, 857
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 878,660,945,548,857, is 1.
Now, the common factors can be found like this.
878:2x 439
660:2x 2x 3x 5x 11
945:3x 3x 3x 5x 7
548:2x 2x 137
857:857
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 3x 5 = 120
Therefore, the value for common factors is 120.
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 = 257176712469600/(1x120)
LCM = 257176712469600/120
LCM = 2143139270580
Thus, we can understand that the LCM of 878,660,945,548,857 is 2143139270580.
