Find LCM of 281,459,646,783,327 with Prime Factorization
| 3 | 281, 459, 646, 783, 327 |
| 3 | 281, 153, 646, 261, 109 |
| 3 | 281, 51, 646, 87, 109 |
| 17 | 281, 17, 646, 29, 109 |
| 281, 1, 38, 29, 109 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 3 x 17 x 281 x 1 x 38 x 29 x 109 = 15492699522
Therefore, the lowest common multiple of 281,459,646,783,327 is 15492699522.
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.
281 x 459 x 646 x 783 x 327 = 21333447241794
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.
281 : 1, 281
459 : 1, 3, 9, 17, 27, 51, 153, 459
646 : 1, 2, 17, 19, 34, 38, 323, 646
783 : 1, 3, 9, 27, 29, 87, 261, 783
327 : 1, 3, 109, 327
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 281,459,646,783,327, is 1.
Now, the common factors can be found like this.
281:281
459:3x 3x 3x 17
646:2x 17x 19
783:3x 3x 3x 29
327:3x 109
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 3x 17 = 1377
Therefore, the value for common factors is 1377.
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 = 21333447241794/(1x1377)
LCM = 21333447241794/1377
LCM = 15492699522
Thus, we can understand that the LCM of 281,459,646,783,327 is 15492699522.
