Given numbers are 810,810,108,251
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 810,810,108,251 is 406620.
Find LCM of 810,810,108,251 with Prime Factorization
| 2 | 810, 810, 108, 251 |
| 3 | 405, 405, 54, 251 |
| 3 | 135, 135, 18, 251 |
| 3 | 45, 45, 6, 251 |
| 3 | 15, 15, 2, 251 |
| 5 | 5, 5, 2, 251 |
| 1, 1, 2, 251 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 3 x 5 x 1 x 1 x 2 x 251 = 406620
Therefore, the lowest common multiple of 810,810,108,251 is 406620.
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.
810 x 810 x 108 x 251 = 17785558800
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.
810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810
810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810
108 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 108
251 : 1, 251
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 810,810,108,251, is 1.
Now, the common factors can be found like this.
810:2x 3x 3x 3x 3x 5
810:2x 3x 3x 3x 3x 5
108:2x 2x 3x 3x 3
251:251
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 3x 3x 3x 3x 3x 5 = 43740
Therefore, the value for common factors is 43740.
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 = 17785558800/(1x43740)
LCM = 17785558800/43740
LCM = 406620
Thus, we can understand that the LCM of 810,810,108,251 is 406620.
