Given numbers are 311,684,285,580
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 311,684,285,580 is 30844980.
Find LCM of 311,684,285,580 with Prime Factorization
| 2 | 311, 684, 285, 580 |
| 2 | 311, 342, 285, 290 |
| 3 | 311, 171, 285, 145 |
| 5 | 311, 57, 95, 145 |
| 19 | 311, 57, 19, 29 |
| 311, 3, 1, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 19 x 311 x 3 x 1 x 29 = 30844980
Therefore, the lowest common multiple of 311,684,285,580 is 30844980.
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.
311 x 684 x 285 x 580 = 35163277200
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.
311 : 1, 311
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
285 : 1, 3, 5, 15, 19, 57, 95, 285
580 : 1, 2, 4, 5, 10, 20, 29, 58, 116, 145, 290, 580
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 311,684,285,580, is 1.
Now, the common factors can be found like this.
311:311
684:2x 2x 3x 3x 19
285:3x 5x 19
580:2x 2x 5x 29
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 5x 19 = 1140
Therefore, the value for common factors is 1140.
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 = 35163277200/(1x1140)
LCM = 35163277200/1140
LCM = 30844980
Thus, we can understand that the LCM of 311,684,285,580 is 30844980.
