The issue of the number of factors to be retained in a factor analysis has been an undefined. Be that as it may, this paper tries to x-ray the number of factors (k) to be retained in a factor analysis for different sample sizes using the method of Principal Factor estimation when the number of variables are ten (10). Stimulated data were used for sample sizes of 30, 50 and 70 and the Akaike Information Criterion (AIC), the Schwarz Information Criterion (SIC) and the Hannan Quinne Information Criterion (HQIC) values were obtained when the number of factors(k) are two, three, and five (2,3 and 5). It was discorvered that the AIC, SIC, and HQIC values are smallest when k = 5, and highest when k = 2 for the sample sizes of 30 and 70. But, for a sample of 50, the values of these information criteria is smallest for k = 3, highest for k=5. Hence, conclusion is drawn that for the sample sizes of 30 and 70, the optimal number of factors to retain is 5 and 3 for the sample size of 70. This implies that, the number of factors to retain is a function of the sample size of the data.
