Given numbers are 687,315,794,234,584
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 687,315,794,234,584 is 217416621240.
Find LCM of 687,315,794,234,584 with Prime Factorization
| 2 | 687, 315, 794, 234, 584 |
| 3 | 687, 315, 397, 117, 292 |
| 3 | 229, 105, 397, 39, 292 |
| 229, 35, 397, 13, 292 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 229 x 35 x 397 x 13 x 292 = 217416621240
Therefore, the lowest common multiple of 687,315,794,234,584 is 217416621240.
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 315 x 794 x 234 x 584 = 23480995093920
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
315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
794 : 1, 2, 397, 794
234 : 1, 2, 3, 6, 9, 13, 18, 26, 39, 78, 117, 234
584 : 1, 2, 4, 8, 73, 146, 292, 584
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 687,315,794,234,584, is 1.
Now, the common factors can be found like this.
687:3x 229
315:3x 3x 5x 7
794:2x 397
234:2x 3x 3x 13
584:2x 2x 2x 73
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 3x 3 = 108
Therefore, the value for common factors is 108.
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 = 23480995093920/(1x108)
LCM = 23480995093920/108
LCM = 217416621240
Thus, we can understand that the LCM of 687,315,794,234,584 is 217416621240.
