Given numbers are 810,721,606,311,355
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 810,721,606,311,355 is 1302448005810.
Find LCM of 810,721,606,311,355 with Prime Factorization
| 2 | 810, 721, 606, 311, 355 |
| 3 | 405, 721, 303, 311, 355 |
| 5 | 135, 721, 101, 311, 355 |
| 27, 721, 101, 311, 71 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 27 x 721 x 101 x 311 x 71 = 1302448005810
Therefore, the lowest common multiple of 810,721,606,311,355 is 1302448005810.
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 721 x 606 x 311 x 355 = 39073440174300
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
721 : 1, 7, 103, 721
606 : 1, 2, 3, 6, 101, 202, 303, 606
311 : 1, 311
355 : 1, 5, 71, 355
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 810,721,606,311,355, is 1.
Now, the common factors can be found like this.
810:2x 3x 3x 3x 3x 5
721:7x 103
606:2x 3x 101
311:311
355:5x 71
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 5 = 30
Therefore, the value for common factors is 30.
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 = 39073440174300/(1x30)
LCM = 39073440174300/30
LCM = 1302448005810
Thus, we can understand that the LCM of 810,721,606,311,355 is 1302448005810.
