Given numbers are 417,377,814,638
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 417,377,814,638 is 127968126.
Find LCM of 417,377,814,638 with Prime Factorization
| 2 | 417, 377, 814, 638 |
| 11 | 417, 377, 407, 319 |
| 29 | 417, 377, 37, 29 |
| 417, 13, 37, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 29 x 417 x 13 x 37 x 1 = 127968126
Therefore, the lowest common multiple of 417,377,814,638 is 127968126.
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.
417 x 377 x 814 x 638 = 81643664388
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.
417 : 1, 3, 139, 417
377 : 1, 13, 29, 377
814 : 1, 2, 11, 22, 37, 74, 407, 814
638 : 1, 2, 11, 22, 29, 58, 319, 638
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 417,377,814,638, is 1.
Now, the common factors can be found like this.
417:3x 139
377:13x 29
814:2x 11x 37
638:2x 11x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11x 29 = 638
Therefore, the value for common factors is 638.
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 = 81643664388/(1x638)
LCM = 81643664388/638
LCM = 127968126
Thus, we can understand that the LCM of 417,377,814,638 is 127968126.
