Quick Answer: How Many Prime Factors Does 30 Have?

Why is 30 not a perfect square?

Is 30 a perfect square number.

A number is a perfect square (or a square number) if its square root is an integer; that is to say, it is the product of an integer with itself.

Here, the square root of 30 is about 5.477.

Thus, the square root of 30 is not an integer, and therefore 30 is not a square number..

How many prime factors can a number have?

There are an infinite number of prime numbers, so there is no upper bound to how many prime factors a number can have. Even if there were just one prime number, x, that could be multiplied by itself repeatedly to give numbers that had successively greater numbers of prime factors.

What is the largest prime factor of 36?

For example, the number 36 can be written as a product of primes as: 36 = 2² x 3². The expression 2² x 3² is said to be the prime factorization of 36. The Fundamental Theorem of Arithmetic states that every composite number can be factored uniquely (except for the order of the factors) into a product of prime factors.

Is 9 a perfect square?

In mathematics, a square number or perfect square is an integer that is the square of an integer; in other words, it is the product of some integer with itself. For example, 9 is a square number, since it can be written as 3 × 3.
