Find LCM of 427,976,885,356,640 with Prime Factorization
| 2 | 427, 976, 885, 356, 640 |
| 2 | 427, 488, 885, 178, 320 |
| 2 | 427, 244, 885, 89, 160 |
| 2 | 427, 122, 885, 89, 80 |
| 5 | 427, 61, 885, 89, 40 |
| 61 | 427, 61, 177, 89, 8 |
| 7, 1, 177, 89, 8 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 5 x 61 x 7 x 1 x 177 x 89 x 8 = 4304979840
Therefore, the lowest common multiple of 427,976,885,356,640 is 4304979840.
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.
427 x 976 x 885 x 356 x 640 = 84033206476800
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.
427 : 1, 7, 61, 427
976 : 1, 2, 4, 8, 16, 61, 122, 244, 488, 976
885 : 1, 3, 5, 15, 59, 177, 295, 885
356 : 1, 2, 4, 89, 178, 356
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 427,976,885,356,640, is 1.
Now, the common factors can be found like this.
427:7x 61
976:2x 2x 2x 2x 61
885:3x 5x 59
356:2x 2x 89
640:2x 2x 2x 2x 2x 2x 2x 5
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 61 = 19520
Therefore, the value for common factors is 19520.
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 = 84033206476800/(1x19520)
LCM = 84033206476800/19520
LCM = 4304979840
Thus, we can understand that the LCM of 427,976,885,356,640 is 4304979840.
