36,201 is not a prime number because 3 is one of its factors. 3 is one of the factors of any number whose digits add up to 3 or a multiple of 3. The only prime number with 3 as one of its factors is the number 3.

A prime number is a whole number that has two factors which are itself and one. where as, A composite number has factors in addition to one and itself.

1617 is not a prime number. The sum of its digits is a multiple of 3, so 3 is one of its factors. A prime number has exactly two factors, 1 and the number itself, so 1617 is a composite number.

It is a multiple of 500.

No.3 is less than 5, thus cannot be a multiple of it; 3 is prime, therefore cannot be a multiple of any number besides 3 (which is one of its factors); by definition, 3 is ismply not a multiple of any number but 1 and 3.
