Given numbers are 405,969,406,261
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 405,969,406,261 is 53110890.
Find LCM of 405,969,406,261 with Prime Factorization
| 3 | 405, 969, 406, 261 |
| 3 | 135, 323, 406, 87 |
| 29 | 45, 323, 406, 29 |
| 45, 323, 14, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 29 x 45 x 323 x 14 x 1 = 53110890
Therefore, the lowest common multiple of 405,969,406,261 is 53110890.
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.
405 x 969 x 406 x 261 = 41585826870
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.
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
969 : 1, 3, 17, 19, 51, 57, 323, 969
406 : 1, 2, 7, 14, 29, 58, 203, 406
261 : 1, 3, 9, 29, 87, 261
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 405,969,406,261, is 1.
Now, the common factors can be found like this.
405:3x 3x 3x 3x 5
969:3x 17x 19
406:2x 7x 29
261:3x 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.
3x 3x 3x 29 = 783
Therefore, the value for common factors is 783.
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 = 41585826870/(1x783)
LCM = 41585826870/783
LCM = 53110890
Thus, we can understand that the LCM of 405,969,406,261 is 53110890.
