The challenge code reads:
```pythonimport sysimport astdef check_factors(a,b,ab):    if abs(a)<=1 or abs(b)<=1:        print("too easy")        return False    if type(a*b) == float:        print("no floats please")        return False    return a*b == ab 
factors = [4,10,0x123120,38201373467,247867822373,422943922809193529087,3741]
for composite in factors:    print(f"Factor {composite}")    a = ast.literal_eval(input("a:").strip())    b = ast.literal_eval(input("b:").strip())     if check_factors(a,b,composite):
        continue    breakelse:    print("Here is your Flag. Good Job!")    print(open("flag.txt").read())
```
We need to factorize the integers from the list.We can solve this by hand, entering the prompted numbers into a factorization tool such as: https://www.numberempire.com/numberfactorizer.phpProviding valid factors for all integers in one go lets us receive the flag.
