1266: gcd和lcm(Java) WUSTOJ 1266: gcd和lcm 参考 1naive1的博客 Description 已知a,b的最大公约数为x,也即gcd(a,b)=x; a,b的最小公倍数为y,也即lcm(a,b)=y.给出x,y.求满足要求的a和b一共有多少种。 Input 多组测试样例。每组给两个整数x,y.(1<=x<=100000,1<=y<=100...
System.out.println(a / gcd(a,b) * b); // LCM = ab / gcd(a,b) } static int gcd(int a, int b) { if (b == 0) return a; return gcd(b, a % b); } } 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14. 15. 16. 17....
Given two positive integers G and L, could you tell me how many solutions of (x, y, z) there are, satisfying that gcd(x, y, z) = G and lcm(x, y, z) = L? Note, gcd(x, y, z) means the greatest common divisor of x, y and z, while lcm(x, y, z) means the least ...
