Given numbers are 256,741,228,717
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 256,741,228,717 is 45337344.
Find LCM of 256,741,228,717 with Prime Factorization
| 2 | 256, 741, 228, 717 |
| 2 | 128, 741, 114, 717 |
| 3 | 64, 741, 57, 717 |
| 19 | 64, 247, 19, 239 |
| 64, 13, 1, 239 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 19 x 64 x 13 x 1 x 239 = 45337344
Therefore, the lowest common multiple of 256,741,228,717 is 45337344.
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.
256 x 741 x 228 x 717 = 31010743296
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.
256 : 1, 2, 4, 8, 16, 32, 64, 128, 256
741 : 1, 3, 13, 19, 39, 57, 247, 741
228 : 1, 2, 3, 4, 6, 12, 19, 38, 57, 76, 114, 228
717 : 1, 3, 239, 717
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 256,741,228,717, is 1.
Now, the common factors can be found like this.
256:2x 2x 2x 2x 2x 2x 2x 2
741:3x 13x 19
228:2x 2x 3x 19
717:3x 239
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 19 = 684
Therefore, the value for common factors is 684.
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 = 31010743296/(1x684)
LCM = 31010743296/684
LCM = 45337344
Thus, we can understand that the LCM of 256,741,228,717 is 45337344.
