Given numbers are 300,495,810,815
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 300,495,810,815 is 14523300.
Find LCM of 300,495,810,815 with Prime Factorization
| 2 | 300, 495, 810, 815 |
| 3 | 150, 495, 405, 815 |
| 3 | 50, 165, 135, 815 |
| 5 | 50, 55, 45, 815 |
| 10, 11, 9, 163 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 10 x 11 x 9 x 163 = 14523300
Therefore, the lowest common multiple of 300,495,810,815 is 14523300.
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.
300 x 495 x 810 x 815 = 98032275000
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.
300 : 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 25, 30, 50, 60, 75, 100, 150, 300
495 : 1, 3, 5, 9, 11, 15, 33, 45, 55, 99, 165, 495
810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810
815 : 1, 5, 163, 815
5 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 300,495,810,815, is 5.
Now, the common factors can be found like this.
300:2x 2x 3x 5x 5
495:3x 3x 5x 11
810:2x 3x 3x 3x 3x 5
815:5x 163
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 3x 5x 5 = 1350
Therefore, the value for common factors is 1350.
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 = 98032275000/(5x1350)
LCM = 98032275000/6750
LCM = 14523300
Thus, we can understand that the LCM of 300,495,810,815 is 14523300.
