Given numbers are 729,228,790,831,343
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 729,228,790,831,343 is 2079275830380.
Find LCM of 729,228,790,831,343 with Prime Factorization
| 2 | 729, 228, 790, 831, 343 |
| 3 | 729, 114, 395, 831, 343 |
| 243, 38, 395, 277, 343 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 243 x 38 x 395 x 277 x 343 = 2079275830380
Therefore, the lowest common multiple of 729,228,790,831,343 is 2079275830380.
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.
729 x 228 x 790 x 831 x 343 = 37426964946840
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.
729 : 1, 3, 9, 27, 81, 243, 729
228 : 1, 2, 3, 4, 6, 12, 19, 38, 57, 76, 114, 228
790 : 1, 2, 5, 10, 79, 158, 395, 790
831 : 1, 3, 277, 831
343 : 1, 7, 49, 343
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 729,228,790,831,343, is 1.
Now, the common factors can be found like this.
729:3x 3x 3x 3x 3x 3
228:2x 2x 3x 19
790:2x 5x 79
831:3x 277
343:7x 7x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3 = 18
Therefore, the value for common factors is 18.
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 = 37426964946840/(1x18)
LCM = 37426964946840/18
LCM = 2079275830380
Thus, we can understand that the LCM of 729,228,790,831,343 is 2079275830380.
