Question: What is the sum of the distinct prime factors of $210$? - Redraw

Understanding the Context

In recent years, discussions around prime numbers and their roles in real-world systems have grown. From encryption securing online transactions to cybersecurity protecting digital identities, prime factor analysis underpins trust in modern infrastructure. For curious learners and professionals alike, the straightforward question about $210$ opens a portal to these deeper concepts. Unlike flashy trends, this kind of foundational math supports long-term financial and technological awareness—especially in an era where digital literacy shapes economic confidence and personal responsibility.

How to Calculate the Sum of Distinct Prime Factors of $210$

To find the sum, begin by identifying the prime factors of $210$. Prime factorization breaks $210$ into its indivisible components. Start by dividing $210$ by the smallest prime, $2$: $210 ÷ 2 = 105$. Next, $105$ is divisible by $3$ ($105 ÷ 3 = 35$), and $35$ factors into $5$ and $7$. So, $210 = 2 × 3 × 5 × 7$. These four primes—$2$, $3$, $5$, and $7$—are distinct, meaning each appears only once in the factorization.

Adding them together: $2 + 3 + 5 + 7 = 17$. That’s the final sum—a small number with significant real-world implications, especially in areas like investment algorithms, digital security, and educational tools designed to spark analytical thinking.
