Given numbers are 311,971,868,806,272
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 311,971,868,806,272 is 231713645072.
Find LCM of 311,971,868,806,272 with Prime Factorization
| 2 | 311, 971, 868, 806, 272 |
| 2 | 311, 971, 434, 403, 136 |
| 31 | 311, 971, 217, 403, 68 |
| 311, 971, 7, 13, 68 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 31 x 311 x 971 x 7 x 13 x 68 = 231713645072
Therefore, the lowest common multiple of 311,971,868,806,272 is 231713645072.
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.
311 x 971 x 868 x 806 x 272 = 57464983977856
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.
311 : 1, 311
971 : 1, 971
868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868
806 : 1, 2, 13, 26, 31, 62, 403, 806
272 : 1, 2, 4, 8, 16, 17, 34, 68, 136, 272
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 311,971,868,806,272, is 1.
Now, the common factors can be found like this.
311:311
971:971
868:2x 2x 7x 31
806:2x 13x 31
272:2x 2x 2x 2x 17
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 31 = 248
Therefore, the value for common factors is 248.
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 = 57464983977856/(1x248)
LCM = 57464983977856/248
LCM = 231713645072
Thus, we can understand that the LCM of 311,971,868,806,272 is 231713645072.
