28 is not a prime number because it is divisible by 2, 4, 7, and 14. Prime numbers are only divisible by 1 and themselves without any other factors.
To find the prime factors of 28 start with any factor pair of 28 and keep factoring the composite factors until all the factors are prime. 28 2 x 14 2 x 2 x 7 The three prime factors of 28 are 2, 2, 7.
No two numbers have the exact same factors.

Among the factors of 28, 2 and 7 are the only prime numbers.
Presumably you mean the prime factors, which are 2 and 7
The prime numbers (factors) of 28 are: 2 and 7
28 is not a prime number because it is divisible by 2, 4, 7, and 14. Prime numbers are only divisible by 1 and themselves without any other factors.

As a product of its prime factors: 2*2*7 = 28
They are: 1 2 4 7 14 and 28 note that 2 and 7 are prime numbers
It means splitting the number into the primes that when multiplied together make the original number. For example the prime factorisation of 28 is 2 x 2 x 7 since 2 x 2 x 7 = 28. This prime factorization of 28 could be written as 22 x 7 using powers to collate (collect together) multiple copies of the same prime.
No two numbers have the exact same factors.
25 and 28 are both multiples of 1. The prime factors of 25 are 5 and 5. The prime factors of 28 are 2, 2, and 7. The two numbers do not share any prime factors, so their greatest common divisor is 1.
Answer: The factors of 28 are: 1 2 4 7 14 28 The prime factors are: 2 x 2 x 7
