Given numbers are 405,845,524,401,309
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 405,845,524,401,309 is 1481339529540.
Find LCM of 405,845,524,401,309 with Prime Factorization
| 3 | 405, 845, 524, 401, 309 |
| 5 | 135, 845, 524, 401, 103 |
| 27, 169, 524, 401, 103 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 27 x 169 x 524 x 401 x 103 = 1481339529540
Therefore, the lowest common multiple of 405,845,524,401,309 is 1481339529540.
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 845 x 524 x 401 x 309 = 22220092943100
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
845 : 1, 5, 13, 65, 169, 845
524 : 1, 2, 4, 131, 262, 524
401 : 1, 401
309 : 1, 3, 103, 309
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 405,845,524,401,309, is 1.
Now, the common factors can be found like this.
405:3x 3x 3x 3x 5
845:5x 13x 13
524:2x 2x 131
401:401
309:3x 103
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5 = 15
Therefore, the value for common factors is 15.
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 = 22220092943100/(1x15)
LCM = 22220092943100/15
LCM = 1481339529540
Thus, we can understand that the LCM of 405,845,524,401,309 is 1481339529540.
