What is the Smallest Prime Factor of 91?
When exploring number theory, one intriguing question arises: What is the smallest prime factor of 91? Understanding prime factors helps unlock deeper insights into divisibility, factorization, and properties of numbers—skills valuable in math, cryptography, and problem-solving.
Breaking Down 91: A Step-by-Step Approach
Understanding the Context
To find the smallest prime factor of 91, start by recalling that a prime factor is a prime number that divides 91 exactly without leaving a remainder. We analyze how 91 breaks down:
-
Check divisibility by the smallest prime: 2
91 is odd, so it is not divisible by 2.
→ Not a prime factor. -
Try the next prime: 3
Add digits: 9 + 1 = 10. Since 10 is not divisible by 3, 91 is not divisible by 3.
→ Not a prime factor. -
Next prime: 5
91 does not end in 0 or 5, so it’s not divisible by 5.
→ Not a prime factor.
Key Insights
- Check divisibility by 7
Perform division:
91 ÷ 7 = 13
Since 7 × 13 = 91, 7 divides 91 evenly.
Both 7 and 13 are prime numbers.
The Answer: The Smallest Prime Factor of 91
Among the prime factors of 91—7 and 13—the smallest is 7.
Thus, the smallest prime factor of 91 is 7.
