Given numbers are 405,725,601,521,145
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 405,725,601,521,145 is 18388030725.
Find LCM of 405,725,601,521,145 with Prime Factorization
| 5 | 405, 725, 601, 521, 145 |
| 29 | 81, 145, 601, 521, 29 |
| 81, 5, 601, 521, 1 |
Multiply the prime numbers at the bottom and the left side.
5 x 29 x 81 x 5 x 601 x 521 x 1 = 18388030725
Therefore, the lowest common multiple of 405,725,601,521,145 is 18388030725.
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 725 x 601 x 521 x 145 = 13331322275625
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
725 : 1, 5, 25, 29, 145, 725
601 : 1, 601
521 : 1, 521
145 : 1, 5, 29, 145
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 405,725,601,521,145, is 1.
Now, the common factors can be found like this.
405:3x 3x 3x 3x 5
725:5x 5x 29
601:601
521:521
145:5x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 5x 29 = 725
Therefore, the value for common factors is 725.
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 = 13331322275625/(1x725)
LCM = 13331322275625/725
LCM = 18388030725
Thus, we can understand that the LCM of 405,725,601,521,145 is 18388030725.
