6 is not a prime number but it is a factor of 72
6 is not a factor of 80. 6 is not a prime number.
6
12 isn't a prime factor, since it has 2, 3, 4, & 6 to multiply.
Both 6 and 9 have the number 3 as a prime factor. 6 = 3 x 2 9 = 3 x 3
Prime number refers to what they are; prime factor refers to what they do. A number doesn't become a factor until it is multiplied. 2 and 3 are prime numbers. 2 and 3 are prime factors of 6.
No, they have a common factor, 2.
The prime factors of 2 are: Well, 2 has no prime factors because 2 is a prime number The prime factors of 6 are: 1, 2, 3, & 6
The prime factor of 7 is 7. The prime factor of 8 is 2. The prime factor of 9 is 3. The prime factors of 10 are 2 and 5. The prime factor of 11 is 11.
'64' = 2^(5) NB 2^(6) = 128
It is a factor of 132, not a prime 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.
