Given numbers are 6615,6993
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 6615,6993 is 244755.
Find LCM of 6615,6993 with Prime Factorization
| 3 | 6615, 6993 |
| 3 | 2205, 2331 |
| 3 | 735, 777 |
| 7 | 245, 259 |
| 35, 37 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 3 x 7 x 35 x 37 = 244755
Therefore, the lowest common multiple of 6615,6993 is 244755.
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.
6615 x 6993 = 46258695
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.
6615 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 49, 63, 105, 135, 147, 189, 245, 315, 441, 735, 945, 1323, 2205, 6615
6993 : 1, 3, 7, 9, 21, 27, 37, 63, 111, 189, 259, 333, 777, 999, 2331, 6993
189 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 6615,6993, is 189.
Now, the common factors can be found like this.
6615:3x 3x 3x 5x 7x 7
6993:3x 3x 3x 7x 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 = 46258695/(189x1)
LCM = 46258695/189
LCM = 244755
Thus, we can understand that the LCM of 6615,6993 is 244755.
