Understanding these factors is crucial for simplifying mathematical expressions and solving equations involving the number 25.
(1, 25): Multiplying 1 by 25 gives 25. This shows that 1 and 25 are factor pairs.
(5, 5): Multiplying 5 by 5 equals 25. This demonstrates that 25 is a perfect square.
(-1, -25): Multiplying -1 by -25 also results in 25. This pair shows that the product of two negative factors is positive.
(-5, -5): Multiplying -5 by -5 equals 25. This further confirms the perfect square property with negative factors.
Calculating the prime factors of a number involves breaking it down into its prime components. Prime factors are prime numbers that, when multiplied together, give the original number. Here’s how to determine the prime factors of 25:
Begin with the smallest prime number, which is 2. Check if 25 is divisible by 2. Since 25 is odd, it is not divisible by 2.
Check if 25 is divisible by 3. The sum of the digits (2 + 5 = 7) is not divisible by 3, so 25 is not divisible by 3.
Check if 25 is divisible by 5. Since 25 ends in 5, it is divisible by 5. Divide 25 by 5, which gives 5. Therefore, 5 is a prime factor of 25.
Divide 5 by 5 again, which results in 1. This confirms that 25 can be expressed as 5 × 5.
