Factors of 42 are the numbers which divide 42 exactly without any remainder. Hence, the factors of 42 are 1, 2, 3, 6, 7, 14, 21, and 42. Prime factors of 42 are 1, 2, 3, and 7.
Is 240 a prime or composite number?
240 is a composite number. Prime factorization: 240 = 2 x 2 x 2 x 2 x 3 x 5, which can be written 2⁴ x 3 x 5. The exponents in the prime factorization are 4, 1 and 1. Adding one to each and multiplying we get (4 + 1)(1 + 1)(1 + 1) = 5 x 2 x 2 = 20.
What are the odd factors of 240?
Out of 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 48, 60, 80, 120, and 240, we have 1, 3, 5, and 15 which are not divisible by 2. So, they are odd. Hence, the odd factors of 240 are 1, 3, 5, and 15.
How to write prime factorization for the number 240?
If we put all of it together we have the factors 2 x 2 x 2 x 2 x 3 x 5 = 240. It can also be written in exponential form as 2 4 x 3 1 x 5 1 .

Which is the result of a prime factorization?
A prime factorization is the result of factoring a number into a set of components which every member is a prime number. This is generally written by showing 240 as a product of its prime factors. For 240, this result would be: Is 240 a composite number?
Can a number be factored into a prime number?
This theorem states that natural numbers greater than 1 are either prime, or can be factored as a product of prime numbers. As an example, the number 60 can be factored into a product of prime numbers as follows:
