Given numbers are 465,806,864,865
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 465,806,864,865 is 301186080.
Find LCM of 465,806,864,865 with Prime Factorization
| 2 | 465, 806, 864, 865 |
| 3 | 465, 403, 432, 865 |
| 5 | 155, 403, 144, 865 |
| 31 | 31, 403, 144, 173 |
| 1, 13, 144, 173 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 31 x 1 x 13 x 144 x 173 = 301186080
Therefore, the lowest common multiple of 465,806,864,865 is 301186080.
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.
465 x 806 x 864 x 865 = 280103054400
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.
465 : 1, 3, 5, 15, 31, 93, 155, 465
806 : 1, 2, 13, 26, 31, 62, 403, 806
864 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 32, 36, 48, 54, 72, 96, 108, 144, 216, 288, 432, 864
865 : 1, 5, 173, 865
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 465,806,864,865, is 1.
Now, the common factors can be found like this.
465:3x 5x 31
806:2x 13x 31
864:2x 2x 2x 2x 2x 3x 3x 3
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.
2x 3x 5x 31 = 930
Therefore, the value for common factors is 930.
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 = 280103054400/(1x930)
LCM = 280103054400/930
LCM = 301186080
Thus, we can understand that the LCM of 465,806,864,865 is 301186080.
