Does every composite number only have two prime factors?
no, because a composite number can be found by multiplying three prime numbers. 3*2*5 = 30, and 30 is a composite number and also has 3 prime factors. Every prime number has 1 prime factor by the way, itself. 1 is neither prime nor composite.
What is the difference between prime factorization and finding a factor?
A factor of a composite number need not be a prime number, some factors are themselves composite. Prime factorisation is continuing to factorise each factor unless it is a prime. For example, start with 30. 6 goes into 30 so finding a factor is satisfied by simply identifying 6 as a factor of 30. Now 30 = 5*6 where 5 is a prime, but 6 is not so we need to factorise 6. 6 = 2*3 and therefore, 30 = 5*2*3 = 2*3*5 The last is the prime factorisation of 30.
Is 30 031 a prime number?
30,031 is composite.
Is 30 and 135 prime or composite?
30 and 135 are composite numbers. A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1 and 0. 1 and 0 are neither prime, nor composite.
What is the prime or composite for 30?
30 is composite.
