Find LCM of 128,560,822,809,456 with Prime Factorization
| 2 | 128, 560, 822, 809, 456 |
| 2 | 64, 280, 411, 809, 228 |
| 2 | 32, 140, 411, 809, 114 |
| 2 | 16, 70, 411, 809, 57 |
| 3 | 8, 35, 411, 809, 57 |
| 8, 35, 137, 809, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 8 x 35 x 137 x 809 x 19 = 28302314880
Therefore, the lowest common multiple of 128,560,822,809,456 is 28302314880.
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.
128 x 560 x 822 x 809 x 456 = 21736177827840
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.
128 : 1, 2, 4, 8, 16, 32, 64, 128
560 : 1, 2, 4, 5, 7, 8, 10, 14, 16, 20, 28, 35, 40, 56, 70, 80, 112, 140, 280, 560
822 : 1, 2, 3, 6, 137, 274, 411, 822
809 : 1, 809
456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,560,822,809,456, is 1.
Now, the common factors can be found like this.
128:2x 2x 2x 2x 2x 2x 2
560:2x 2x 2x 2x 5x 7
822:2x 3x 137
809:809
456:2x 2x 2x 3x 19
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 2x 2x 3 = 768
Therefore, the value for common factors is 768.
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 = 21736177827840/(1x768)
LCM = 21736177827840/768
LCM = 28302314880
Thus, we can understand that the LCM of 128,560,822,809,456 is 28302314880.
