Given numbers are 310,400,447,391,867
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 310,400,447,391,867 is 36842991600.
Find LCM of 310,400,447,391,867 with Prime Factorization
| 2 | 310, 400, 447, 391, 867 |
| 3 | 155, 200, 447, 391, 867 |
| 5 | 155, 200, 149, 391, 289 |
| 17 | 31, 40, 149, 391, 289 |
| 31, 40, 149, 23, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 17 x 31 x 40 x 149 x 23 x 17 = 36842991600
Therefore, the lowest common multiple of 310,400,447,391,867 is 36842991600.
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.
310 x 400 x 447 x 391 x 867 = 18789925716000
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.
310 : 1, 2, 5, 10, 31, 62, 155, 310
400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400
447 : 1, 3, 149, 447
391 : 1, 17, 23, 391
867 : 1, 3, 17, 51, 289, 867
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 310,400,447,391,867, is 1.
Now, the common factors can be found like this.
310:2x 5x 31
400:2x 2x 2x 2x 5x 5
447:3x 149
391:17x 23
867:3x 17x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 5x 17 = 510
Therefore, the value for common factors is 510.
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 = 18789925716000/(1x510)
LCM = 18789925716000/510
LCM = 36842991600
Thus, we can understand that the LCM of 310,400,447,391,867 is 36842991600.
