Given numbers are 547,687,315,315,162
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 547,687,315,315,162 is 710241210.
Find LCM of 547,687,315,315,162 with Prime Factorization
| 3 | 547, 687, 315, 315, 162 |
| 3 | 547, 229, 105, 105, 54 |
| 5 | 547, 229, 35, 35, 18 |
| 7 | 547, 229, 7, 7, 18 |
| 547, 229, 1, 1, 18 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 7 x 547 x 229 x 1 x 1 x 18 = 710241210
Therefore, the lowest common multiple of 547,687,315,315,162 is 710241210.
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.
547 x 687 x 315 x 315 x 162 = 6040601491050
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.
547 : 1, 547
687 : 1, 3, 229, 687
315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
162 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 547,687,315,315,162, is 1.
Now, the common factors can be found like this.
547:547
687:3x 229
315:3x 3x 5x 7
315:3x 3x 5x 7
162:2x 3x 3x 3x 3
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 3x 3x 3x 5x 7 = 8505
Therefore, the value for common factors is 8505.
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 = 6040601491050/(1x8505)
LCM = 6040601491050/8505
LCM = 710241210
Thus, we can understand that the LCM of 547,687,315,315,162 is 710241210.
