# Who am I?

Number Theory Level pending

I am the number that is divisible by $$20$$ the original number. If I multiplied by $$12$$, the result will be divisible by $$42$$ the original number. If I multiplied by $$45$$, the result will be divisible by $$80$$ the original number. Suppose I was $$n$$, specify many of the original numbers that divide $$21n^ 3$$.
