Given numbers are 687,582,215,330
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 687,582,215,330 is 315202470.
Find LCM of 687,582,215,330 with Prime Factorization
| 2 | 687, 582, 215, 330 |
| 3 | 687, 291, 215, 165 |
| 5 | 229, 97, 215, 55 |
| 229, 97, 43, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 229 x 97 x 43 x 11 = 315202470
Therefore, the lowest common multiple of 687,582,215,330 is 315202470.
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.
687 x 582 x 215 x 330 = 28368222300
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.
687 : 1, 3, 229, 687
582 : 1, 2, 3, 6, 97, 194, 291, 582
215 : 1, 5, 43, 215
330 : 1, 2, 3, 5, 6, 10, 11, 15, 22, 30, 33, 55, 66, 110, 165, 330
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 687,582,215,330, is 1.
Now, the common factors can be found like this.
687:3x 229
582:2x 3x 97
215:5x 43
330:2x 3x 5x 11
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 3x 5 = 90
Therefore, the value for common factors is 90.
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 = 28368222300/(1x90)
LCM = 28368222300/90
LCM = 315202470
Thus, we can understand that the LCM of 687,582,215,330 is 315202470.
