Given numbers are 515,309,129,387
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 515,309,129,387 is 199305.
Find LCM of 515,309,129,387 with Prime Factorization
| 3 | 515, 309, 129, 387 |
| 43 | 515, 103, 43, 129 |
| 103 | 515, 103, 1, 3 |
| 5, 1, 1, 3 |
Multiply the prime numbers at the bottom and the left side.
3 x 43 x 103 x 5 x 1 x 1 x 3 = 199305
Therefore, the lowest common multiple of 515,309,129,387 is 199305.
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.
515 x 309 x 129 x 387 = 7944496605
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.
515 : 1, 5, 103, 515
309 : 1, 3, 103, 309
129 : 1, 3, 43, 129
387 : 1, 3, 9, 43, 129, 387
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 515,309,129,387, is 1.
Now, the common factors can be found like this.
515:5x 103
309:3x 103
129:3x 43
387:3x 3x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 43x 103 = 39861
Therefore, the value for common factors is 39861.
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 = 7944496605/(1x39861)
LCM = 7944496605/39861
LCM = 199305
Thus, we can understand that the LCM of 515,309,129,387 is 199305.
