Given numbers are 349,881,720,687,285
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 349,881,720,687,285 is 963214285680.
Find LCM of 349,881,720,687,285 with Prime Factorization
| 3 | 349, 881, 720, 687, 285 |
| 5 | 349, 881, 240, 229, 95 |
| 349, 881, 48, 229, 19 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 349 x 881 x 48 x 229 x 19 = 963214285680
Therefore, the lowest common multiple of 349,881,720,687,285 is 963214285680.
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.
349 x 881 x 720 x 687 x 285 = 43344642855600
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.
349 : 1, 349
881 : 1, 881
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
687 : 1, 3, 229, 687
285 : 1, 3, 5, 15, 19, 57, 95, 285
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 349,881,720,687,285, is 1.
Now, the common factors can be found like this.
349:349
881:881
720:2x 2x 2x 2x 3x 3x 5
687:3x 229
285:3x 5x 19
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 5 = 45
Therefore, the value for common factors is 45.
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 = 43344642855600/(1x45)
LCM = 43344642855600/45
LCM = 963214285680
Thus, we can understand that the LCM of 349,881,720,687,285 is 963214285680.
