Given numbers are 418,891,196,668,928
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 418,891,196,668,928 is 128555846496.
Find LCM of 418,891,196,668,928 with Prime Factorization
| 2 | 418, 891, 196, 668, 928 |
| 2 | 209, 891, 98, 334, 464 |
| 11 | 209, 891, 49, 167, 232 |
| 19, 81, 49, 167, 232 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 19 x 81 x 49 x 167 x 232 = 128555846496
Therefore, the lowest common multiple of 418,891,196,668,928 is 128555846496.
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.
418 x 891 x 196 x 668 x 928 = 45251657966592
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.
418 : 1, 2, 11, 19, 22, 38, 209, 418
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
196 : 1, 2, 4, 7, 14, 28, 49, 98, 196
668 : 1, 2, 4, 167, 334, 668
928 : 1, 2, 4, 8, 16, 29, 32, 58, 116, 232, 464, 928
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 418,891,196,668,928, is 1.
Now, the common factors can be found like this.
418:2x 11x 19
891:3x 3x 3x 3x 11
196:2x 2x 7x 7
668:2x 2x 167
928:2x 2x 2x 2x 2x 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 2x 2x 2x 2x 11 = 352
Therefore, the value for common factors is 352.
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 = 45251657966592/(1x352)
LCM = 45251657966592/352
LCM = 128555846496
Thus, we can understand that the LCM of 418,891,196,668,928 is 128555846496.
