Find LCM of 247,338,551,903,390 with Prime Factorization
| 2 | 247, 338, 551, 903, 390 |
| 3 | 247, 169, 551, 903, 195 |
| 13 | 247, 169, 551, 301, 65 |
| 19 | 19, 13, 551, 301, 5 |
| 1, 13, 29, 301, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 19 x 1 x 13 x 29 x 301 x 5 = 840864570
Therefore, the lowest common multiple of 247,338,551,903,390 is 840864570.
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.
247 x 338 x 551 x 903 x 390 = 16200096805620
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.
247 : 1, 13, 19, 247
338 : 1, 2, 13, 26, 169, 338
551 : 1, 19, 29, 551
903 : 1, 3, 7, 21, 43, 129, 301, 903
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 247,338,551,903,390, is 1.
Now, the common factors can be found like this.
247:13x 19
338:2x 13x 13
551:19x 29
903:3x 7x 43
390:2x 3x 5x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 13x 13x 19 = 19266
Therefore, the value for common factors is 19266.
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 = 16200096805620/(1x19266)
LCM = 16200096805620/19266
LCM = 840864570
Thus, we can understand that the LCM of 247,338,551,903,390 is 840864570.
