The number is 875 and its prime factors are 5; 5; 5 & 7.
Well, the factors of a prime number is that they only have two factors.
1617 is not a prime number. The sum of its digits is a multiple of 3, so 3 is one of its factors. A prime number has exactly two factors, 1 and the number itself, so 1617 is a composite number.
36,201 is not a prime number because 3 is one of its factors. 3 is one of the factors of any number whose digits add up to 3 or a multiple of 3. The only prime number with 3 as one of its factors is the number 3.
A prime number with identical digits is 11.

This question doesn't quite make sense; a prime number has no factors.If you meant a prime whose digits sum to 10 it is 37.

All numbers have factors. Some factors are prime numbers. These are known as prime factors. The set of prime factors is a subset of the set of factors for any given number.
No difference. Once you've found the factors of a number, the prime numbers on that list are the prime factors.

The prime number is 47 and 4+7 = 11
No, by inspection it is even (2 is one of the factors), also by sum of digits, 9 is one of the factors. Either of these is enough to show that it is not prime.
