Given numbers are 218,218,198
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 218,218,198 is 21582.
Find LCM of 218,218,198 with Prime Factorization
| 2 | 218, 218, 198 |
| 109 | 109, 109, 99 |
| 1, 1, 99 |
Multiply the prime numbers at the bottom and the left side.
2 x 109 x 1 x 1 x 99 = 21582
Therefore, the lowest common multiple of 218,218,198 is 21582.
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.
218 x 218 x 198 = 9409752
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.
218 : 1, 2, 109, 218
218 : 1, 2, 109, 218
198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 218,218,198, is 2.
Now, the common factors can be found like this.
218:2x 109
218:2x 109
198:2x 3x 3x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 109 = 218
Therefore, the value for common factors is 218.
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 = 9409752/(2x218)
LCM = 9409752/436
LCM = 21582
Thus, we can understand that the LCM of 218,218,198 is 21582.
