Given numbers are 858,902,578,816
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 858,902,578,816 is 81331536.
Find LCM of 858,902,578,816 with Prime Factorization
| 2 | 858, 902, 578, 816 |
| 3 | 429, 451, 289, 408 |
| 11 | 143, 451, 289, 136 |
| 17 | 13, 41, 289, 136 |
| 13, 41, 17, 8 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 17 x 13 x 41 x 17 x 8 = 81331536
Therefore, the lowest common multiple of 858,902,578,816 is 81331536.
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.
858 x 902 x 578 x 816 = 365015933568
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.
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
902 : 1, 2, 11, 22, 41, 82, 451, 902
578 : 1, 2, 17, 34, 289, 578
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 858,902,578,816, is 2.
Now, the common factors can be found like this.
858:2x 3x 11x 13
902:2x 11x 41
578:2x 17x 17
816:2x 2x 2x 2x 3x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3x 11x 17 = 2244
Therefore, the value for common factors is 2244.
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 = 365015933568/(2x2244)
LCM = 365015933568/4488
LCM = 81331536
Thus, we can understand that the LCM of 858,902,578,816 is 81331536.
