Given numbers are 271,455,793,390
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 271,455,793,390 is 45129630.
Find LCM of 271,455,793,390 with Prime Factorization
| 5 | 271, 455, 793, 390 |
| 13 | 271, 91, 793, 78 |
| 271, 7, 61, 6 |
Multiply the prime numbers at the bottom and the left side.
5 x 13 x 271 x 7 x 61 x 6 = 45129630
Therefore, the lowest common multiple of 271,455,793,390 is 45129630.
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.
271 x 455 x 793 x 390 = 38134537350
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.
271 : 1, 271
455 : 1, 5, 7, 13, 35, 65, 91, 455
793 : 1, 13, 61, 793
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 271,455,793,390, is 1.
Now, the common factors can be found like this.
271:271
455:5x 7x 13
793:13x 61
390:2x 3x 5x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 13x 13 = 845
Therefore, the value for common factors is 845.
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 = 38134537350/(1x845)
LCM = 38134537350/845
LCM = 45129630
Thus, we can understand that the LCM of 271,455,793,390 is 45129630.
