31 is a prime number, but 24 and 35 are not.
31/35, as 31 is a prime number.
These are the composites between 31 and 41: 32, 33, 34, 35, 36, 38, 39, 40.
32+33+34+35+36 (31 is a prime number) = 170
The only prime number between 30 and 35 is 31.
A prime number has exactly two factors.The factors of 31 are 1 and 31, so it is a prime number.The factors of 35 are 1, 5, 7, and 35, so it is not a prime number.The factors of 24 are 1, 2, 3, 4, 6, 8, 12, and 24, so it is not a prime number.The only prime number among 31, 35, and 24 is 31.
You basically check different numbers, until you find one that is prime. For example, starting at some odd number, say 31, check several odd numbers (31, 33, 35, 37, 39, ...) and see if it is a prime number.
21 = 3x7 23 = prime 25 = 5x5 27 = 3x9 29 = prime 31 = prime 33 = 3x11 35 = 5x7 37 = prime 39 = 3x13
24 is divisible by 2 and 35 is divisible by 5. 31 has only two factors: 1 and itself. 31 is the prime number.
There are two: 29 and 31
All of them except for 31 and 37 which are prime numbers
They are 29 and 31
