Find LCM of 115,667,641,144,240 with Prime Factorization
| 2 | 115, 667, 641, 144, 240 |
| 2 | 115, 667, 641, 72, 120 |
| 2 | 115, 667, 641, 36, 60 |
| 2 | 115, 667, 641, 18, 30 |
| 3 | 115, 667, 641, 9, 15 |

| 23 | 23, 667, 641, 3, 1 |
| 1, 29, 641, 3, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 5 x 23 x 1 x 29 x 641 x 3 x 1 = 307833840
Therefore, the lowest common multiple of 115,667,641,144,240 is 307833840.
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.
115 x 667 x 641 x 144 x 240 = 1699242796800
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.
115 : 1, 5, 23, 115
667 : 1, 23, 29, 667
641 : 1, 641
144 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, 144
240 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 115,667,641,144,240, is 1.
Now, the common factors can be found like this.
115:5x 23
667:23x 29
641:641
144:2x 2x 2x 2x 3x 3
240:2x 2x 2x 2x 3x 5
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 3x 5x 23 = 5520
Therefore, the value for common factors is 5520.
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 = 1699242796800/(1x5520)
LCM = 1699242796800/5520
LCM = 307833840
Thus, we can understand that the LCM of 115,667,641,144,240 is 307833840.
