Given numbers are 786,726,940,924
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 786,726,940,924 is 312898740.
Find LCM of 786,726,940,924 with Prime Factorization
| 2 | 786, 726, 940, 924 |
| 2 | 393, 363, 470, 462 |
| 3 | 393, 363, 235, 231 |
| 11 | 131, 121, 235, 77 |
| 131, 11, 235, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 11 x 131 x 11 x 235 x 7 = 312898740
Therefore, the lowest common multiple of 786,726,940,924 is 312898740.
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.
786 x 726 x 940 x 924 = 495631604160
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.
786 : 1, 2, 3, 6, 131, 262, 393, 786
726 : 1, 2, 3, 6, 11, 22, 33, 66, 121, 242, 363, 726
940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940
924 : 1, 2, 3, 4, 6, 7, 11, 12, 14, 21, 22, 28, 33, 42, 44, 66, 77, 84, 132, 154, 231, 308, 462, 924
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 786,726,940,924, is 2.
Now, the common factors can be found like this.
786:2x 3x 131
726:2x 3x 11x 11
940:2x 2x 5x 47
924:2x 2x 3x 7x 11
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 3x 3x 11 = 792
Therefore, the value for common factors is 792.
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 = 495631604160/(2x792)
LCM = 495631604160/1584
LCM = 312898740
Thus, we can understand that the LCM of 786,726,940,924 is 312898740.
