Find LCM of 828,805,551,985,903 with Prime Factorization
| 3 | 828, 805, 551, 985, 903 |
| 5 | 276, 805, 551, 985, 301 |
| 7 | 276, 161, 551, 197, 301 |
| 23 | 276, 23, 551, 197, 43 |
| 12, 1, 551, 197, 43 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 7 x 23 x 12 x 1 x 551 x 197 x 43 = 135264758580
Therefore, the lowest common multiple of 828,805,551,985,903 is 135264758580.
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.
828 x 805 x 551 x 985 x 903 = 326664391970700
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.
828 : 1, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828
805 : 1, 5, 7, 23, 35, 115, 161, 805
551 : 1, 19, 29, 551
985 : 1, 5, 197, 985
903 : 1, 3, 7, 21, 43, 129, 301, 903
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 828,805,551,985,903, is 1.
Now, the common factors can be found like this.
828:2x 2x 3x 3x 23
805:5x 7x 23
551:19x 29
985:5x 197
903:3x 7x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 7x 23 = 2415
Therefore, the value for common factors is 2415.
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 = 326664391970700/(1x2415)
LCM = 326664391970700/2415
LCM = 135264758580
Thus, we can understand that the LCM of 828,805,551,985,903 is 135264758580.
