How many divisors does 432 have?

two divisorsThe list of all positive divisors (i.e., the list of all integers that divide 432) is as follows: 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432. For 432 to be a prime number, it would have been required that 432 has only two divisors, i.e., itself and 1.

IS 144 a perfect square?

A number is a perfect square (or asquare number) if its square root is an integer; that is to say, it is the product of an integer with itself. Here, thesquare root of 144 is 12. Therefore, thesquare root of 144 is an integer, and as a consequence 144 is a perfect square.

What is the greatest common factor of 144?

144:1, 144, 2, 72, 3, 48, 4, 36, 6, 24, 8, 18, 9, 16, 12. 1, 2, and 4 are the only factors that are common to 36, 64, and 144. Since 4 is the greatest of these factors, it is the correct answer.

What can go into 432?
