Given numbers are 284,418,247,315,164
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 284,418,247,315,164 is 9965575620.
Find LCM of 284,418,247,315,164 with Prime Factorization
| 2 | 284, 418, 247, 315, 164 |
| 2 | 142, 209, 247, 315, 82 |
| 19 | 71, 209, 247, 315, 41 |
| 71, 11, 13, 315, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 19 x 71 x 11 x 13 x 315 x 41 = 9965575620
Therefore, the lowest common multiple of 284,418,247,315,164 is 9965575620.
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.
284 x 418 x 247 x 315 x 164 = 1514767494240
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.
284 : 1, 2, 4, 71, 142, 284
418 : 1, 2, 11, 19, 22, 38, 209, 418
247 : 1, 13, 19, 247
315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
164 : 1, 2, 4, 41, 82, 164
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 284,418,247,315,164, is 1.
Now, the common factors can be found like this.
284:2x 2x 71
418:2x 11x 19
247:13x 19
315:3x 3x 5x 7
164:2x 2x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 19 = 152
Therefore, the value for common factors is 152.
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 = 1514767494240/(1x152)
LCM = 1514767494240/152
LCM = 9965575620
Thus, we can understand that the LCM of 284,418,247,315,164 is 9965575620.
