Question: What is the smallest prime factor of 165? - RTA

Understanding the Context

This math query reflects a broader interest in clarity and efficiency—whether evaluating investment risks, calculating returns, or simplifying financial literacy. For US users navigating personal finance, small-pattern understanding fosters informed decision-making, primes critical thinking, and builds numeracy confidence. It’s not just number crunching; it’s about recognizing patterns that support smarter choices. Regardless of background, understanding core concepts like prime factors empowers people to engage thoughtfully with data-driven topics.

How Does the Smallest Prime Factor of 165 Work?

The smallest prime factor of 165 is 3. To identify this, start by testing divisibility using the smallest primes. 165 is clearly odd, so not divisible by 2. Adding its digits (1 + 6 + 5 = 12) shows it’s divisible by 3—since 12 is divisible by 3, so too is 165. Performing the division: 165 ÷ 3 = 55. So, 3 is the smallest prime factor. No smaller prime (2, 3 included as first check) divides 165 cleanly—proof that 3 wins the title with clarity and mathematical precision.
