Given numbers are 408,340,515,885
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 408,340,515,885 is 12397080.
Find LCM of 408,340,515,885 with Prime Factorization
| 2 | 408, 340, 515, 885 |
| 2 | 204, 170, 515, 885 |
| 3 | 102, 85, 515, 885 |
| 5 | 34, 85, 515, 295 |
| 17 | 34, 17, 103, 59 |
| 2, 1, 103, 59 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 17 x 2 x 1 x 103 x 59 = 12397080
Therefore, the lowest common multiple of 408,340,515,885 is 12397080.
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.
408 x 340 x 515 x 885 = 63225108000
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.
408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408
340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340
515 : 1, 5, 103, 515
885 : 1, 3, 5, 15, 59, 177, 295, 885
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 408,340,515,885, is 1.
Now, the common factors can be found like this.
408:2x 2x 2x 3x 17
340:2x 2x 5x 17
515:5x 103
885:3x 5x 59
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3x 5x 5x 17 = 5100
Therefore, the value for common factors is 5100.
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 = 63225108000/(1x5100)
LCM = 63225108000/5100
LCM = 12397080
Thus, we can understand that the LCM of 408,340,515,885 is 12397080.
