Given numbers are 311,170,108,186
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 311,170,108,186 is 88504380.
Find LCM of 311,170,108,186 with Prime Factorization
| 2 | 311, 170, 108, 186 |
| 3 | 311, 85, 54, 93 |
| 311, 85, 18, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 311 x 85 x 18 x 31 = 88504380
Therefore, the lowest common multiple of 311,170,108,186 is 88504380.
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 170 x 108 x 186 = 1062052560
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
170 : 1, 2, 5, 10, 17, 34, 85, 170
108 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 108
186 : 1, 2, 3, 6, 31, 62, 93, 186
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 311,170,108,186, is 1.
Now, the common factors can be found like this.
311:311
170:2x 5x 17
108:2x 2x 3x 3x 3
186:2x 3x 31
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 3 = 12
Therefore, the value for common factors is 12.
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 = 1062052560/(1x12)
LCM = 1062052560/12
LCM = 88504380
Thus, we can understand that the LCM of 311,170,108,186 is 88504380.
