Answer: 1, 5, 25, 125, and 625.
Step-by-step explanation: The prime factorization of 625 is 5^4, which means 625 has a total of (4+1) = 5 factors.
To determine the number of factors of a given number, we can take the prime factorization of that number and add 1 to each exponent of the primes, then multiply those results together. In this case, the prime factorization of 625 is 5^4, so the number of factors is (4+1) = 5.
The factors of 625 are: 1, 5, 25, 125, and 625.
