Given numbers are 391,957,927,901,687
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 391,957,927,901,687 is 1403325854271.
Find LCM of 391,957,927,901,687 with Prime Factorization
| 3 | 391, 957, 927, 901, 687 |
| 17 | 391, 319, 309, 901, 229 |
| 23, 319, 309, 53, 229 |
Multiply the prime numbers at the bottom and the left side.
3 x 17 x 23 x 319 x 309 x 53 x 229 = 1403325854271
Therefore, the lowest common multiple of 391,957,927,901,687 is 1403325854271.
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.
391 x 957 x 927 x 901 x 687 = 214708855703463
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.
391 : 1, 17, 23, 391
957 : 1, 3, 11, 29, 33, 87, 319, 957
927 : 1, 3, 9, 103, 309, 927
901 : 1, 17, 53, 901
687 : 1, 3, 229, 687
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,957,927,901,687, is 1.
Now, the common factors can be found like this.
391:17x 23
957:3x 11x 29
927:3x 3x 103
901:17x 53
687:3x 229
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 17 = 153
Therefore, the value for common factors is 153.
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 = 214708855703463/(1x153)
LCM = 214708855703463/153
LCM = 1403325854271
Thus, we can understand that the LCM of 391,957,927,901,687 is 1403325854271.
