Given numbers are 815,336,581,311,550
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 815,336,581,311,550 is 388774755600.
Find LCM of 815,336,581,311,550 with Prime Factorization
| 2 | 815, 336, 581, 311, 550 |
| 5 | 815, 168, 581, 311, 275 |
| 7 | 163, 168, 581, 311, 55 |
| 163, 24, 83, 311, 55 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 163 x 24 x 83 x 311 x 55 = 388774755600
Therefore, the lowest common multiple of 815,336,581,311,550 is 388774755600.
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.
815 x 336 x 581 x 311 x 550 = 27214232892000
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.
815 : 1, 5, 163, 815
336 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 42, 48, 56, 84, 112, 168, 336
581 : 1, 7, 83, 581
311 : 1, 311
550 : 1, 2, 5, 10, 11, 22, 25, 50, 55, 110, 275, 550
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 815,336,581,311,550, is 1.
Now, the common factors can be found like this.
815:5x 163
336:2x 2x 2x 2x 3x 7
581:7x 83
311:311
550:2x 5x 5x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 7 = 70
Therefore, the value for common factors is 70.
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 = 27214232892000/(1x70)
LCM = 27214232892000/70
LCM = 388774755600
Thus, we can understand that the LCM of 815,336,581,311,550 is 388774755600.
