Find LCM of 368,687,885,240 with Prime Factorization
| 2 | 368, 687, 885, 240 |
| 2 | 184, 687, 885, 120 |
| 2 | 92, 687, 885, 60 |
| 2 | 46, 687, 885, 30 |
| 3 | 23, 687, 885, 15 |
| 5 | 23, 229, 295, 5 |
| 23, 229, 59, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 5 x 23 x 229 x 59 x 1 = 74580720
Therefore, the lowest common multiple of 368,687,885,240 is 74580720.
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.
368 x 687 x 885 x 240 = 53698118400
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.
368 : 1, 2, 4, 8, 16, 23, 46, 92, 184, 368
687 : 1, 3, 229, 687
885 : 1, 3, 5, 15, 59, 177, 295, 885
240 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 368,687,885,240, is 1.
Now, the common factors can be found like this.
368:2x 2x 2x 2x 23
687:3x 229
885:3x 5x 59
240:2x 2x 2x 2x 3x 5
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 2x 2x 3x 3x 5 = 720
Therefore, the value for common factors is 720.
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 = 53698118400/(1x720)
LCM = 53698118400/720
LCM = 74580720
Thus, we can understand that the LCM of 368,687,885,240 is 74580720.
