The LCM of 871,558,990,560 is 1496935440.
Find LCM of 871,558,990,560 with Prime Factorization
| 2 | 871, 558, 990, 560 |
| 3 | 871, 279, 495, 280 |
| 3 | 871, 93, 165, 280 |
| 5 | 871, 31, 55, 280 |
| 871, 31, 11, 56 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 871 x 31 x 11 x 56 = 1496935440
Therefore, the lowest common multiple of 871,558,990,560 is 1496935440.
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.
871 x 558 x 990 x 560 = 269448379200
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.
871 : 1, 13, 67, 871
558 : 1, 2, 3, 6, 9, 18, 31, 62, 93, 186, 279, 558
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
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 871,558,990,560, is 1.
Now, the common factors can be found like this.
871:13x 67
558:2x 3x 3x 31
990:2x 3x 3x 5x 11
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 3x 3x 5 = 180
Therefore, the value for common factors is 180.
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 = 269448379200/(1x180)
LCM = 269448379200/180
LCM = 1496935440
Thus, we can understand that the LCM of 871,558,990,560 is 1496935440.
