The LCM of 307,920,748,920,311 is 16425863080.
Find LCM of 307,920,748,920,311 with Prime Factorization
| 2 | 307, 920, 748, 920, 311 |
| 2 | 307, 460, 374, 460, 311 |
| 2 | 307, 230, 187, 230, 311 |
| 5 | 307, 115, 187, 115, 311 |
| 23 | 307, 23, 187, 23, 311 |
| 307, 1, 187, 1, 311 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 23 x 307 x 1 x 187 x 1 x 311 = 16425863080
Therefore, the lowest common multiple of 307,920,748,920,311 is 16425863080.
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.
307 x 920 x 748 x 920 x 311 = 60447176134400
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.
307 : 1, 307
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
311 : 1, 311
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 307,920,748,920,311, is 1.
Now, the common factors can be found like this.
307:307
920:2x 2x 2x 5x 23
748:2x 2x 11x 17
920:2x 2x 2x 5x 23
311:311
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 2x 2x 5x 23 = 3680
Therefore, the value for common factors is 3680.
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 = 60447176134400/(1x3680)
LCM = 60447176134400/3680
LCM = 16425863080
Thus, we can understand that the LCM of 307,920,748,920,311 is 16425863080.
