Given numbers are 605,687,144,229
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 605,687,144,229 is 19950480.
Find LCM of 605,687,144,229 with Prime Factorization
| 3 | 605, 687, 144, 229 |
| 229 | 605, 229, 48, 229 |
| 605, 1, 48, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 229 x 605 x 1 x 48 x 1 = 19950480
Therefore, the lowest common multiple of 605,687,144,229 is 19950480.
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.
605 x 687 x 144 x 229 = 13705979760
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.
605 : 1, 5, 11, 55, 121, 605
687 : 1, 3, 229, 687
144 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, 144
229 : 1, 229
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 605,687,144,229, is 1.
Now, the common factors can be found like this.
605:5x 11x 11
687:3x 229
144:2x 2x 2x 2x 3x 3
229:229
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 229 = 687
Therefore, the value for common factors is 687.
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 = 13705979760/(1x687)
LCM = 13705979760/687
LCM = 19950480
Thus, we can understand that the LCM of 605,687,144,229 is 19950480.
