Given numbers are 280,218,760,436,571
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 280,218,760,436,571 is 331111480.
Find LCM of 280,218,760,436,571 with Prime Factorization
| 2 | 280, 218, 760, 436, 571 |
| 2 | 140, 109, 380, 218, 571 |
| 2 | 70, 109, 190, 109, 571 |
| 5 | 35, 109, 95, 109, 571 |
| 109 | 7, 109, 19, 109, 571 |
| 7, 1, 19, 1, 571 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 109 x 7 x 1 x 19 x 1 x 571 = 331111480
Therefore, the lowest common multiple of 280,218,760,436,571 is 331111480.
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.
280 x 218 x 760 x 436 x 571 = 11549168422400
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.
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
218 : 1, 2, 109, 218
760 : 1, 2, 4, 5, 8, 10, 19, 20, 38, 40, 76, 95, 152, 190, 380, 760
436 : 1, 2, 4, 109, 218, 436
571 : 1, 571
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 280,218,760,436,571, is 1.
Now, the common factors can be found like this.
280:2x 2x 2x 5x 7
218:2x 109
760:2x 2x 2x 5x 19
436:2x 2x 109
571:571
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 2x 2x 2x 5x 109 = 34880
Therefore, the value for common factors is 34880.
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 = 11549168422400/(1x34880)
LCM = 11549168422400/34880
LCM = 331111480
Thus, we can understand that the LCM of 280,218,760,436,571 is 331111480.
