Given numbers are 812,136,664,696
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 812,136,664,696 is 6874392.
Find LCM of 812,136,664,696 with Prime Factorization
| 2 | 812, 136, 664, 696 |
| 2 | 406, 68, 332, 348 |
| 2 | 203, 34, 166, 174 |
| 29 | 203, 17, 83, 87 |
| 7, 17, 83, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 29 x 7 x 17 x 83 x 3 = 6874392
Therefore, the lowest common multiple of 812,136,664,696 is 6874392.
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.
812 x 136 x 664 x 696 = 51035486208
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.
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
136 : 1, 2, 4, 8, 17, 34, 68, 136
664 : 1, 2, 4, 8, 83, 166, 332, 664
696 : 1, 2, 3, 4, 6, 8, 12, 24, 29, 58, 87, 116, 174, 232, 348, 696
4 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 812,136,664,696, is 4.
Now, the common factors can be found like this.
812:2x 2x 7x 29
136:2x 2x 2x 17
664:2x 2x 2x 83
696:2x 2x 2x 3x 29
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 2x 2x 29 = 1856
Therefore, the value for common factors is 1856.
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 = 51035486208/(4x1856)
LCM = 51035486208/7424
LCM = 6874392
Thus, we can understand that the LCM of 812,136,664,696 is 6874392.
