A captcha is not considered a factor in multi-factor authentication because it is a challenge-response test to determine whether the user is human, rather than a factor that verifies the identity of the user. Multi-factor authentication typically involves something you know (password), something you have (ID card), and something you are (biometric data like a fingerprint).
