Given numbers are 386,166,858,747,422
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 386,166,858,747,422 is 8700143166.
Find LCM of 386,166,858,747,422 with Prime Factorization
| 2 | 386, 166, 858, 747, 422 |
| 3 | 193, 83, 429, 747, 211 |
| 83 | 193, 83, 143, 249, 211 |
| 193, 1, 143, 3, 211 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 83 x 193 x 1 x 143 x 3 x 211 = 8700143166
Therefore, the lowest common multiple of 386,166,858,747,422 is 8700143166.
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.
386 x 166 x 858 x 747 x 422 = 17330685186672
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.
386 : 1, 2, 193, 386
166 : 1, 2, 83, 166
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
747 : 1, 3, 9, 83, 249, 747
422 : 1, 2, 211, 422
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 386,166,858,747,422, is 1.
Now, the common factors can be found like this.
386:2x 193
166:2x 83
858:2x 3x 11x 13
747:3x 3x 83
422:2x 211
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 3x 83 = 1992
Therefore, the value for common factors is 1992.
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 = 17330685186672/(1x1992)
LCM = 17330685186672/1992
LCM = 8700143166
Thus, we can understand that the LCM of 386,166,858,747,422 is 8700143166.
