সবচেয়ে ক্ষুদ্রতম সংখ্যা নির্ণয় কর যাকে মোট 24 টি সংখ্যা দিয়ে নিঃশেষে ভাগ করা যায়।

if u mean positive integer,then it is 24!

my smallest answer till now is $420$
the divisors are $1,2,3,4,5,84,6,7,10,12,14,15,20,21,28,30,35,42,60,70,105,70,210,420$
there are $26$ divisors
but, i think there is a smaller number.

ans is 420

i have got the exact answer:-)it is 360 whose prime factorization is 2^3*3^2*5 which ensures its minimality.

Yes, the right answer is $360$. Because 2,3,5 are the lowest prime numbers. Now use Divisor Function
If have the book Theory Of Numbers ---- by John e couri and Andrew adlar then see the book. Or without having book you can see this link. I think this is also useful for you.

I admit that the right ans is 360.But it can be more less like -360.It also have 24 divisors.Isn't it correct. Give me advice if I am wrong

If you consider negative integers,then you must count negative factors.Then actually there will be 48 factors,not 24.
