Find LCM of 466,720,240,645,393 with Prime Factorization
| 2 | 466, 720, 240, 645, 393 |
| 2 | 233, 360, 120, 645, 393 |
| 2 | 233, 180, 60, 645, 393 |
| 2 | 233, 90, 30, 645, 393 |
| 3 | 233, 45, 15, 645, 393 |
| 5 | 233, 5, 15, 215, 131 |
| 233, 1, 3, 43, 131 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 5 x 233 x 1 x 3 x 43 x 131 = 944992080
Therefore, the lowest common multiple of 466,720,240,645,393 is 944992080.
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.
466 x 720 x 240 x 645 x 393 = 20411828928000
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.
466 : 1, 2, 233, 466
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
240 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240
645 : 1, 3, 5, 15, 43, 129, 215, 645
393 : 1, 3, 131, 393
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 466,720,240,645,393, is 1.
Now, the common factors can be found like this.
466:2x 233
720:2x 2x 2x 2x 3x 3x 5
240:2x 2x 2x 2x 3x 5
645:3x 5x 43
393:3x 131
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 3x 3x 3x 5x 5 = 21600
Therefore, the value for common factors is 21600.
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 = 20411828928000/(1x21600)
LCM = 20411828928000/21600
LCM = 944992080
Thus, we can understand that the LCM of 466,720,240,645,393 is 944992080.
