Given numbers are 311,189,987,311
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 311,189,987,311 is 2762613.
Find LCM of 311,189,987,311 with Prime Factorization
| 3 | 311, 189, 987, 311 |
| 7 | 311, 63, 329, 311 |
| 311 | 311, 9, 47, 311 |
| 1, 9, 47, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 311 x 1 x 9 x 47 x 1 = 2762613
Therefore, the lowest common multiple of 311,189,987,311 is 2762613.
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 189 x 987 x 311 = 18042625503
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
189 : 1, 3, 7, 9, 21, 27, 63, 189
987 : 1, 3, 7, 21, 47, 141, 329, 987
311 : 1, 311
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 311,189,987,311, is 1.
Now, the common factors can be found like this.
311:311
189:3x 3x 3x 7
987:3x 7x 47
311:311
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7x 311 = 6531
Therefore, the value for common factors is 6531.
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 = 18042625503/(1x6531)
LCM = 18042625503/6531
LCM = 2762613
Thus, we can understand that the LCM of 311,189,987,311 is 2762613.
