What is the greatest common factor of 24 and 28______ The least common multiple is______ ．

24 = 2 × 2 × 2 × 3, 28 = 2 × 2 × 7, so the greatest common divisor of 24 and 28 is 2 × 2 = 4, the least common multiple is 2 × 2 × 2 × 3 × 7 = 168, so the answer is: 4168

Let f (x) = 1 / 2A x ^ 2-lnx (x > 0, a ≠ 0)
(2) Finding f (x) monotone interval
a> 0 don't write it
a

(2)f'(x)=x/a-1/x=(x^2-1)/(ax)
Because a < 0, I) when 0 < x ≤ 1, f '(x) ≥ 0; ii) when x ≥ 1, f' (x) ≤ 0
So when a < 0, f (x) increases monotonically on (0,1) and decreases monotonically on [1, + ∞)
(3) When a ＜ 0, f (x) decreases monotonically on [1, + ∞), because f (x) ＞ 2 is constant on [1,2], so f (2) = 2 / a-ln2 ＞ 2, and a ＜ 2 / (2 + LN2) is obtained
When a > 0, f (x) increases monotonically on [1, + ∞), because f (x) > 2 is constant on [1,2], so f (1) = 1 / (2a) > 2, and a < 1 / 4 is obtained
In conclusion, the range of a is (- ∞, 0) ∪ (0,1 / 4)
