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 c...

GCD and LCM(数论) VJ链接 题意:给出你两个数g和l。问有多少有序数组(x,y,z)满足gcd(x,y,z)=g,lcm(x,y,z)=l 思路: 1.对于(a,b,c),g和l必然存在l%g=0,因为三个数可以写成:a=x1gcd, b=x2gcd, c=x3gcd; l=ab*c/gcd; 显而易见,l%g=0若l%g!=0,不存在满足题意的情况。 2. ...
