Given numbers are 867,342,810,286,191
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 867,342,810,286,191 is 121480303230.
Find LCM of 867,342,810,286,191 with Prime Factorization
| 2 | 867, 342, 810, 286, 191 |
| 3 | 867, 171, 405, 143, 191 |
| 3 | 289, 57, 135, 143, 191 |
| 289, 19, 45, 143, 191 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 289 x 19 x 45 x 143 x 191 = 121480303230
Therefore, the lowest common multiple of 867,342,810,286,191 is 121480303230.
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.
867 x 342 x 810 x 286 x 191 = 13119872748840
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.
867 : 1, 3, 17, 51, 289, 867
342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342
810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810
286 : 1, 2, 11, 13, 22, 26, 143, 286
191 : 1, 191
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 867,342,810,286,191, is 1.
Now, the common factors can be found like this.
867:3x 17x 17
342:2x 3x 3x 19
810:2x 3x 3x 3x 3x 5
286:2x 11x 13
191:191
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 3x 3x 3 = 108
Therefore, the value for common factors is 108.
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 = 13119872748840/(1x108)
LCM = 13119872748840/108
LCM = 121480303230
Thus, we can understand that the LCM of 867,342,810,286,191 is 121480303230.
