Step-by-step explanation:
24 is a composite number.
Prime factorization: 24 = 2 x 2 x 2 x 3, which can be written 24 = 2³ x 3
The exponents in the prime factorization are 3 and 1. Adding one to each and multiplying we get (3 + 1)(1 + 1) = 4 x 2 = 8. Therefore 24 has exactly 8 factors.
Factors of 24: 1, 2, 3, 4, 6, 8, 12, 24
Factor pairs: 24 = 1 x 24, 2 x 12, 3 x 8, or 4 x 6
