Find LCM of 140,667,203,551,920 with Prime Factorization
| 2 | 140, 667, 203, 551, 920 |
| 2 | 70, 667, 203, 551, 460 |
| 5 | 35, 667, 203, 551, 230 |
| 7 | 7, 667, 203, 551, 46 |
| 23 | 1, 667, 29, 551, 46 |
| 29 | 1, 29, 29, 551, 2 |
| 1, 1, 1, 19, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 7 x 23 x 29 x 1 x 1 x 1 x 19 x 2 = 3548440
Therefore, the lowest common multiple of 140,667,203,551,920 is 3548440.
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.
140 x 667 x 203 x 551 x 920 = 9609246488800
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.
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
667 : 1, 23, 29, 667
203 : 1, 7, 29, 203
551 : 1, 19, 29, 551
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 140,667,203,551,920, is 1.
Now, the common factors can be found like this.
140:2x 2x 5x 7
667:23x 29
203:7x 29
551:19x 29
920:2x 2x 2x 5x 23
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 5x 7x 23x 29x 29 = 2708020
Therefore, the value for common factors is 2708020.
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 = 9609246488800/(1x2708020)
LCM = 9609246488800/2708020
LCM = 3548440
Thus, we can understand that the LCM of 140,667,203,551,920 is 3548440.
