# Divisors of 25

The divisors of 25 are 1, 5, and 25. The divisors of 25 are those numbers that completely divide 25 with the remainder zero. Here we will discuss divisors of 25.

## Highlights of Divisors of 25

• Divisors of 25: 1, 5 and 25
• Negative divisors of 25: -1, -5 and -25
• Prime divisors of 25: 5
• Number of divisors of 25: 3
• Sum of divisors of 25: 31
• Product of divisors of 25: 253/2 =125.

## What are the Divisors of 25

Using the rule Dividend ÷ Divisor = Quotient, let us find the list of divisors of 25. Note that we have:

No numbers other than 1, 5, and 25 can divide 25. So the divisors of 25 are 1, 5, and 25. Hence the total number of divisors of 25 is three.

## Properties of Divisors of 25

1. Negative Divisors: We know that if m is a divisor of a number, then -m is also a divisor of that number. As the divisors of 25 are 1, 5, and 25, so the negative divisors of 25 are -1, -5, and –25.
2. Prime Divisors: Among the divisors of 25, only 5 is a prime number. So we conclude that 5 is the only prime divisor of 25.
