Given numbers are 487,268,663,128,439
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 487,268,663,128,439 is 1215603053184.
Find LCM of 487,268,663,128,439 with Prime Factorization
| 2 | 487, 268, 663, 128, 439 |
| 2 | 487, 134, 663, 64, 439 |
| 487, 67, 663, 32, 439 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 487 x 67 x 663 x 32 x 439 = 1215603053184
Therefore, the lowest common multiple of 487,268,663,128,439 is 1215603053184.
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.
487 x 268 x 663 x 128 x 439 = 4862412212736
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.
487 : 1, 487
268 : 1, 2, 4, 67, 134, 268
663 : 1, 3, 13, 17, 39, 51, 221, 663
128 : 1, 2, 4, 8, 16, 32, 64, 128
439 : 1, 439
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 487,268,663,128,439, is 1.
Now, the common factors can be found like this.
487:487
268:2x 2x 67
663:3x 13x 17
128:2x 2x 2x 2x 2x 2x 2
439:439
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 4862412212736/(1x4)
LCM = 4862412212736/4
LCM = 1215603053184
Thus, we can understand that the LCM of 487,268,663,128,439 is 1215603053184.
