Given numbers are 664,816,894,442
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 664,816,894,442 is 131189136.
Find LCM of 664,816,894,442 with Prime Factorization
| 2 | 664, 816, 894, 442 |
| 2 | 332, 408, 447, 221 |
| 2 | 166, 204, 447, 221 |
| 3 | 83, 102, 447, 221 |
| 17 | 83, 34, 149, 221 |
| 83, 2, 149, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 17 x 83 x 2 x 149 x 13 = 131189136
Therefore, the lowest common multiple of 664,816,894,442 is 131189136.
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.
664 x 816 x 894 x 442 = 214100669952
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.
664 : 1, 2, 4, 8, 83, 166, 332, 664
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
894 : 1, 2, 3, 6, 149, 298, 447, 894
442 : 1, 2, 13, 17, 26, 34, 221, 442
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 664,816,894,442, is 2.
Now, the common factors can be found like this.
664:2x 2x 2x 83
816:2x 2x 2x 2x 3x 17
894:2x 3x 149
442:2x 13x 17
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 3x 17 = 816
Therefore, the value for common factors is 816.
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 = 214100669952/(2x816)
LCM = 214100669952/1632
LCM = 131189136
Thus, we can understand that the LCM of 664,816,894,442 is 131189136.
