Video Solution

Step-by-Step Solution

To solve this problem, we need to determine all factors of the number 202.

Step 1: Prime Factorization of 202
To find the prime factors of 202, we begin by dividing by the smallest prime number:

  • 202÷2=101202 \div 2 = 101

Step 2: Check if 101 is prime
101 cannot be divided evenly by any prime numbers up to its square root other than 1 and 101 itself. Therefore, 101 is a prime number.

Therefore, the prime factorization of 202 is 2×1012 \times 101.

Step 3: Listing factors
The factors of a number are all possible products of its prime factors, including 1 and the number itself.

  • Starting with 1 (trivial factor) and ending with the number 202:
  • Single prime 2 gives us two factors: 11 and 22.
  • The factor 101 (as 101×1101 \times 1) is next.
  • Combine 22 and 101101 to get the factor 202202.

Therefore, the factors of 202 are: 1,2,101,1, 2, 101, and 202202.

In conclusion, after comparing with the provided choices, none of the exact choices given fully match as the factors of 202.
