Given numbers are 817,189,831,341,121
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 817,189,831,341,121 is 160439276151.
Find LCM of 817,189,831,341,121 with Prime Factorization
| 3 | 817, 189, 831, 341, 121 |
| 11 | 817, 63, 277, 341, 121 |
| 817, 63, 277, 31, 11 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 817 x 63 x 277 x 31 x 11 = 160439276151
Therefore, the lowest common multiple of 817,189,831,341,121 is 160439276151.
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.
817 x 189 x 831 x 341 x 121 = 5294496112983
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.
817 : 1, 19, 43, 817
189 : 1, 3, 7, 9, 21, 27, 63, 189
831 : 1, 3, 277, 831
341 : 1, 11, 31, 341
121 : 1, 11, 121
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 817,189,831,341,121, is 1.
Now, the common factors can be found like this.
817:19x 43
189:3x 3x 3x 7
831:3x 277
341:11x 31
121:11x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 11 = 33
Therefore, the value for common factors is 33.
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 = 5294496112983/(1x33)
LCM = 5294496112983/33
LCM = 160439276151
Thus, we can understand that the LCM of 817,189,831,341,121 is 160439276151.
