Given numbers are 309,579,168,936
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 309,579,168,936 is 130247208.
Find LCM of 309,579,168,936 with Prime Factorization
| 2 | 309, 579, 168, 936 |
| 2 | 309, 579, 84, 468 |
| 2 | 309, 579, 42, 234 |
| 3 | 309, 579, 21, 117 |
| 103, 193, 7, 39 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 103 x 193 x 7 x 39 = 130247208
Therefore, the lowest common multiple of 309,579,168,936 is 130247208.
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 579 x 168 x 936 = 28133396928
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
579 : 1, 3, 193, 579
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
936 : 1, 2, 3, 4, 6, 8, 9, 12, 13, 18, 24, 26, 36, 39, 52, 72, 78, 104, 117, 156, 234, 312, 468, 936
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 309,579,168,936, is 3.
Now, the common factors can be found like this.
309:3x 103
579:3x 193
168:2x 2x 2x 3x 7
936:2x 2x 2x 3x 3x 13
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 2x 3x 3 = 72
Therefore, the value for common factors is 72.
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 = 28133396928/(3x72)
LCM = 28133396928/216
LCM = 130247208
Thus, we can understand that the LCM of 309,579,168,936 is 130247208.
