Find LCM of 368,861,457,605,256 with Prime Factorization
| 2 | 368, 861, 457, 605, 256 |
| 2 | 184, 861, 457, 605, 128 |
| 2 | 92, 861, 457, 605, 64 |
| 2 | 46, 861, 457, 605, 32 |
| 23, 861, 457, 605, 16 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 23 x 861 x 457 x 605 x 16 = 1401659508480
Therefore, the lowest common multiple of 368,861,457,605,256 is 1401659508480.
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.
368 x 861 x 457 x 605 x 256 = 22426552135680
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.
368 : 1, 2, 4, 8, 16, 23, 46, 92, 184, 368
861 : 1, 3, 7, 21, 41, 123, 287, 861
457 : 1, 457
605 : 1, 5, 11, 55, 121, 605
256 : 1, 2, 4, 8, 16, 32, 64, 128, 256
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 368,861,457,605,256, is 1.
Now, the common factors can be found like this.
368:2x 2x 2x 2x 23
861:3x 7x 41
457:457
605:5x 11x 11
256:2x 2x 2x 2x 2x 2x 2x 2
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 2 = 16
Therefore, the value for common factors is 16.
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 = 22426552135680/(1x16)
LCM = 22426552135680/16
LCM = 1401659508480
Thus, we can understand that the LCM of 368,861,457,605,256 is 1401659508480.
