Given numbers are 7047,8991
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 7047,8991 is 260739.
Find LCM of 7047,8991 with Prime Factorization
| 3 | 7047, 8991 |
| 3 | 2349, 2997 |
| 3 | 783, 999 |
| 3 | 261, 333 |
| 3 | 87, 111 |
| 29, 37 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 3 x 3 x 3 x 29 x 37 = 260739
Therefore, the lowest common multiple of 7047,8991 is 260739.
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.
7047 x 8991 = 63359577
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.
7047 : 1, 3, 9, 27, 29, 81, 87, 243, 261, 783, 2349, 7047
8991 : 1, 3, 9, 27, 37, 81, 111, 243, 333, 999, 2997, 8991
243 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 7047,8991, is 243.
Now, the common factors can be found like this.
7047:3x 3x 3x 3x 3x 29
8991:3x 3x 3x 3x 3x 37
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
= 1
Therefore, the value for common factors is 1.
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 = 63359577/(243x1)
LCM = 63359577/243
LCM = 260739
Thus, we can understand that the LCM of 7047,8991 is 260739.
