Given numbers are 205,831,529,790,172
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 205,831,529,790,172 is 1224520598460.
Find LCM of 205,831,529,790,172 with Prime Factorization
| 2 | 205, 831, 529, 790, 172 |
| 5 | 205, 831, 529, 395, 86 |
| 41, 831, 529, 79, 86 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 41 x 831 x 529 x 79 x 86 = 1224520598460
Therefore, the lowest common multiple of 205,831,529,790,172 is 1224520598460.
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.
205 x 831 x 529 x 790 x 172 = 12245205984600
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.
205 : 1, 5, 41, 205
831 : 1, 3, 277, 831
529 : 1, 23, 529
790 : 1, 2, 5, 10, 79, 158, 395, 790
172 : 1, 2, 4, 43, 86, 172
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 205,831,529,790,172, is 1.
Now, the common factors can be found like this.
205:5x 41
831:3x 277
529:23x 23
790:2x 5x 79
172:2x 2x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5 = 10
Therefore, the value for common factors is 10.
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 = 12245205984600/(1x10)
LCM = 12245205984600/10
LCM = 1224520598460
Thus, we can understand that the LCM of 205,831,529,790,172 is 1224520598460.
