3n+8=a To find the value of n, you need to know the value of a.
It is: 3 plus 97 = 100
3 could be a prime factor but it depends on which number you're trying to find the prime factors of.
It is may be prime only if one term is 2. for example: 3+2=5But one term may be 2 and the result composite: 7+2=9=3*3
Composite. It is divisible by 3 for any n.
Prime Factors: 2, 3 36 = 2 * 2 * 3 * 3
22 + 3 = 7 Since 2 is the only even prime number, this is the only number for which this holds true.
It is: 3 plus 97 = 100
A prime number cannot have any number multiplied to make that number, except for one. example: 9 is not prime because 3 times 3 is 9.

Find a prime number, add 2 to the number. Check if the new number is prime. IE : 3 is prime. 3+2 =5. 5 is prime. (3,5) are twin primes.
The prime factorization of 6 is 2 x 3.
The prime factors of 24 are 2 and 3.
The number 27 has a cube root of 3, which is 2 (the smallest prime) plus 1.
To find a prime number. #1. If an even number (ending in 0,2,4,6,8,) it is NOT a prime number. It is a composite with a factor of '2' #2. An ODD Number ending in '5' is NOT a prime number., It is a composite of '5' #3. If the digits of an ODD number sum to '9' , then it is NOT a prime number, It is a composite of '9' #4. To test for a prime number, divide by '3' & '7' , if there is a remainder to either division it is a prime number. The answer MUST NOT be a whole number. Then it is possible prime number. e.g. 839 #1. NOt EVEN #2 . Does NOT end in '5' #3. The digits sum to 8+3+9 = 20 (Does not divide by ;9;) #4. 839/3 = 279 remainder '2' or 839/7 = 119 remainder '6' So 839 is a prime number.
