2019 AIME I Problem 7
There are positive integers x and y that satisfy the system of equations \log_{10} x + 2 \log_{10} (\gcd(x,y)) = 60 \log_{10} y + 2 \log_{10} (\text{lcm}(x,y)) = 570. Let m be the number of (not necessarily distinct) prime factors in the prime factorization of x, and let n be the number of (not necessarily distinct) prime factors in the prime factorization of y. Find 3m+2n.
Leading zeroes must be inputted, so if your answer is 34, then input 034
