To find a prime factor of a number, divide by 2 and see if you get no remainder. Then divide by 3, 4, 5, and so on, until one of the numbers you try gets you no remainder. If no such numbers work below the number you chose, it is prime. In the case of the number 9, 2 does not go into 9, but 3 does.
9 is not a prime number.
All numbers have factors. Some numbers have some of the same factors as other numbers. These are common factors. If the factor is a prime number, it is a common prime factor. 3 is a prime number. 3 is a factor of 9. 3 is a factor of 12. 3 is a common prime factor of 9 and 12.
The factors of -9 are 1, 3, 9 and their negatives. The prime factor is 3.
The greatest common factor of 63, 81, and 99 is 9.The prime factorization of 63 is 7*9.The prime factorization of 81 is 9*9.The prime factorization of 99 is 11*9.Thus, the greatest of the common factors of 9.
The answer is 7
9 is not a prime factor, but it does have one prime factor, which is three. Prime factors are factors of a number that are prime.
9 is a factor of 36, but it is not prime.
9 is not prime, so it is not a prime factor of 72, great or otherwise.
9 is not a prime number.
