Given numbers are 865,439,489,865
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 865,439,489,865 is 185690415.
Find LCM of 865,439,489,865 with Prime Factorization
| 5 | 865, 439, 489, 865 |
| 173 | 173, 439, 489, 173 |
| 1, 439, 489, 1 |
Multiply the prime numbers at the bottom and the left side.
5 x 173 x 1 x 439 x 489 x 1 = 185690415
Therefore, the lowest common multiple of 865,439,489,865 is 185690415.
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.
865 x 439 x 489 x 865 = 160622208975
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.
865 : 1, 5, 173, 865
439 : 1, 439
489 : 1, 3, 163, 489
865 : 1, 5, 173, 865
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 865,439,489,865, is 1.
Now, the common factors can be found like this.
865:5x 173
439:439
489:3x 163
865:5x 173
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 173 = 865
Therefore, the value for common factors is 865.
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 = 160622208975/(1x865)
LCM = 160622208975/865
LCM = 185690415
Thus, we can understand that the LCM of 865,439,489,865 is 185690415.
