Given numbers are 729,261,909,305
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 729,261,909,305 is 651248505.
Find LCM of 729,261,909,305 with Prime Factorization
| 3 | 729, 261, 909, 305 |
| 3 | 243, 87, 303, 305 |
| 81, 29, 101, 305 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 81 x 29 x 101 x 305 = 651248505
Therefore, the lowest common multiple of 729,261,909,305 is 651248505.
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.
729 x 261 x 909 x 305 = 52751128905
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.
729 : 1, 3, 9, 27, 81, 243, 729
261 : 1, 3, 9, 29, 87, 261
909 : 1, 3, 9, 101, 303, 909
305 : 1, 5, 61, 305
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 729,261,909,305, is 1.
Now, the common factors can be found like this.
729:3x 3x 3x 3x 3x 3
261:3x 3x 29
909:3x 3x 101
305:5x 61
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 3 = 81
Therefore, the value for common factors is 81.
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 = 52751128905/(1x81)
LCM = 52751128905/81
LCM = 651248505
Thus, we can understand that the LCM of 729,261,909,305 is 651248505.
