The LCM of 614,728,856,923 is 1697899112.
Find LCM of 614,728,856,923 with Prime Factorization
| 2 | 614, 728, 856, 923 |
| 2 | 307, 364, 428, 923 |
| 2 | 307, 182, 214, 923 |
| 13 | 307, 91, 107, 923 |
| 307, 7, 107, 71 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 13 x 307 x 7 x 107 x 71 = 1697899112
Therefore, the lowest common multiple of 614,728,856,923 is 1697899112.
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.
614 x 728 x 856 x 923 = 353163015296
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.
614 : 1, 2, 307, 614
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
856 : 1, 2, 4, 8, 107, 214, 428, 856
923 : 1, 13, 71, 923
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 614,728,856,923, is 1.
Now, the common factors can be found like this.
614:2x 307
728:2x 2x 2x 7x 13
856:2x 2x 2x 107
923:13x 71
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 13 = 208
Therefore, the value for common factors is 208.
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 = 353163015296/(1x208)
LCM = 353163015296/208
LCM = 1697899112
Thus, we can understand that the LCM of 614,728,856,923 is 1697899112.
