The LCM of 516,721,952,309 is 12649224.
Find LCM of 516,721,952,309 with Prime Factorization
| 2 | 516, 721, 952, 309 |
| 2 | 258, 721, 476, 309 |
| 3 | 129, 721, 238, 309 |
| 7 | 43, 721, 238, 103 |
| 103 | 43, 103, 34, 103 |
| 43, 1, 34, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 103 x 43 x 1 x 34 x 1 = 12649224
Therefore, the lowest common multiple of 516,721,952,309 is 12649224.
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.
516 x 721 x 952 x 309 = 109441086048
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.
516 : 1, 2, 3, 4, 6, 12, 43, 86, 129, 172, 258, 516
721 : 1, 7, 103, 721
952 : 1, 2, 4, 7, 8, 14, 17, 28, 34, 56, 68, 119, 136, 238, 476, 952
309 : 1, 3, 103, 309
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 516,721,952,309, is 1.
Now, the common factors can be found like this.
516:2x 2x 3x 43
721:7x 103
952:2x 2x 2x 7x 17
309:3x 103
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3x 7x 103 = 8652
Therefore, the value for common factors is 8652.
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 = 109441086048/(1x8652)
LCM = 109441086048/8652
LCM = 12649224
Thus, we can understand that the LCM of 516,721,952,309 is 12649224.
