The LCM of 468,940,923,940 is 7808580.
Find LCM of 468,940,923,940 with Prime Factorization
| 2 | 468, 940, 923, 940 |
| 2 | 234, 470, 923, 470 |
| 5 | 117, 235, 923, 235 |
| 13 | 117, 47, 923, 47 |
| 47 | 9, 47, 71, 47 |
| 9, 1, 71, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 13 x 47 x 9 x 1 x 71 x 1 = 7808580
Therefore, the lowest common multiple of 468,940,923,940 is 7808580.
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.
468 x 940 x 923 x 940 = 381683390400
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.
468 : 1, 2, 3, 4, 6, 9, 12, 13, 18, 26, 36, 39, 52, 78, 117, 156, 234, 468
940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940
923 : 1, 13, 71, 923
940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 468,940,923,940, is 1.
Now, the common factors can be found like this.
468:2x 2x 3x 3x 13
940:2x 2x 5x 47
923:13x 71
940:2x 2x 5x 47
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 5x 13x 47 = 48880
Therefore, the value for common factors is 48880.
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 = 381683390400/(1x48880)
LCM = 381683390400/48880
LCM = 7808580
Thus, we can understand that the LCM of 468,940,923,940 is 7808580.
