The LCM of 855,840,540,382 is 27435240.
Find LCM of 855,840,540,382 with Prime Factorization
| 2 | 855, 840, 540, 382 |
| 2 | 855, 420, 270, 191 |
| 3 | 855, 210, 135, 191 |
| 3 | 285, 70, 45, 191 |
| 5 | 95, 70, 15, 191 |
| 19, 14, 3, 191 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 5 x 19 x 14 x 3 x 191 = 27435240
Therefore, the lowest common multiple of 855,840,540,382 is 27435240.
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.
855 x 840 x 540 x 382 = 148150296000
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.
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540
382 : 1, 2, 191, 382
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 855,840,540,382, is 1.
Now, the common factors can be found like this.
855:3x 3x 5x 19
840:2x 2x 2x 3x 5x 7
540:2x 2x 3x 3x 3x 5
382:2x 191
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 3x 3x 5x 5 = 5400
Therefore, the value for common factors is 5400.
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 = 148150296000/(1x5400)
LCM = 148150296000/5400
LCM = 27435240
Thus, we can understand that the LCM of 855,840,540,382 is 27435240.
