17 is a prime number. 8 and 12 are not prime numbers.
2 and 3 are prime numbers that are factors of 12. There is an infinite list of prime numbers that aren't.
4 and 25 are not prime numbers.
'25' is odd, all right, but not prime. (It can be divided by 1, 5, and 25) By the way, prime numbers must be odd numbers. All even numbers can be divided by 2, at least, and are therefore not prime.
25 percent of the numbers from 1 to 100 are prime numbers.
There are more than 25 prime numbers; there are an infinite number of prime numbers.

25 and 98 are not prime numbers
The sum of the first 25 prime numbers is 1,060.
32 and 25
There are 25 prime numbers between 1 and 100.
The ratio of composite numbers 6,3,4,12,18 and 17 to prime numbers would be 9,15,21 and 25. This is taught in math.
The greatest common factor of 12 and 25 is 1. One way to determine the greatest common factor is to find all the factors of the numbers and compare them. The factors of 12 are 1, 2, 3, 4, 6, and 12. The factors of 25 are 1, 5, and 25. The only common factor is 1. Therefore, the greatest common factor is 1. The numbers are relatively prime. The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together. The prime factors of 12 are 2, 2, and 3. The prime factors of 25 are 5 and 5. There are no prime factors in common, so the numbers are relatively prime, which means the greatest common factor is 1.
There are 25 prime numbers less than 100
The only prime numbers between 25 and 35 are: 29 31.
