Given numbers are 309,469,969,914,942
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 309,469,969,914,942 is 6717067191534.
Find LCM of 309,469,969,914,942 with Prime Factorization
| 2 | 309, 469, 969, 914, 942 |
| 3 | 309, 469, 969, 457, 471 |
| 103, 469, 323, 457, 157 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 103 x 469 x 323 x 457 x 157 = 6717067191534
Therefore, the lowest common multiple of 309,469,969,914,942 is 6717067191534.
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.
309 x 469 x 969 x 914 x 942 = 120907209447612
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.
309 : 1, 3, 103, 309
469 : 1, 7, 67, 469
969 : 1, 3, 17, 19, 51, 57, 323, 969
914 : 1, 2, 457, 914
942 : 1, 2, 3, 6, 157, 314, 471, 942
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 309,469,969,914,942, is 1.
Now, the common factors can be found like this.
309:3x 103
469:7x 67
969:3x 17x 19
914:2x 457
942:2x 3x 157
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 = 120907209447612/(1x18)
LCM = 120907209447612/18
LCM = 6717067191534
Thus, we can understand that the LCM of 309,469,969,914,942 is 6717067191534.
