Given numbers are 289,792,685,805
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 289,792,685,805 is 25242913080.
Find LCM of 289,792,685,805 with Prime Factorization
| 5 | 289, 792, 685, 805 |
| 289, 792, 137, 161 |
Multiply the prime numbers at the bottom and the left side.
5 x 289 x 792 x 137 x 161 = 25242913080
Therefore, the lowest common multiple of 289,792,685,805 is 25242913080.
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.
289 x 792 x 685 x 805 = 126214565400
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.
289 : 1, 17, 289
792 : 1, 2, 3, 4, 6, 8, 9, 11, 12, 18, 22, 24, 33, 36, 44, 66, 72, 88, 99, 132, 198, 264, 396, 792
685 : 1, 5, 137, 685
805 : 1, 5, 7, 23, 35, 115, 161, 805
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 289,792,685,805, is 1.
Now, the common factors can be found like this.
289:17x 17
792:2x 2x 2x 3x 3x 11
685:5x 137
805:5x 7x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5 = 5
Therefore, the value for common factors is 5.
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 = 126214565400/(1x5)
LCM = 126214565400/5
LCM = 25242913080
Thus, we can understand that the LCM of 289,792,685,805 is 25242913080.
