You need to read about basic Exploratory Factor Analysis (EFA) to get idea.

Dear Khursheed

There are many software are suitable to calculate the minimum sample size such as SPSS, SAS, G*Power.

My advice to use G*Powe​r. G*Power software is an effective tool to calculate sample size for many ranges of experiments. Also, you can determine effect size and power of the test, G*Power is free to download and easy to use after reading the manual, the download link:

The link to download G*Power manual:

I hope that be useful for you.

Good Luck

Thank you sir Khalid Hassan I will follow your instructions

Kline suggests that a minimum of two are required for convergence for obvious reasons, but also mentions that more than 4 is excessive and unnecessary. See a citation for the book below:

Kline, R. B. (2015). Principles and practice of structural equation modeling. Guilford publications.

I definitely recommend this book.

With regards to sample size needed to run a factor analysis, there is no agreed sample size although the more the better...however, whatever sample size you decide to use, endeavor to check "KMO and Bartlett's test of sphericity" which measures sampling adequacy" (found Analysis-->Data Reduction-->Factor-->Descriptive in SPSS). A value of >=0.5 is usually considered adequate factor analysis.

All the best.

Thank you respected Muhammed M. Alhaji and Violeta J Rodriguez, for your guidance.
