General Properties of Squares
The square numbers are the values which are produced when we multiply a number by itself. Some of the properties are:
Property 1: The square of a natural number other than one is either a multiple of 3 or exceeds a multiple of 3 by 1.
In other words, a perfect square leaves remainder 0 or 1 on division by 3.
Verification: The above property can be easily verified from the following computations:
| Square number | Remainder when divided by 3 |
| 1 | |
| 0 | |
| 1 | |
| 1 | |
| 0 | |
| 1 | |
| 1 |
Application: If a number when divided by 3 leaves remainder 2, then it is not a perfect square.
Property 2: The square of a natural number other than one is either a multiple of 4 or exceeds a multiple of 4 by 1.
In other words, a perfect square leaves remainder 0 or 1 on division by 4.
Property 3: The square of a natural number n is equal to the sum of first n odd natural numbers.
We have,
Sum of first 1 odd natural number,
Sum of first 2 odd natural numbers,
Sum of first 3 odd natural numbers.
Sum of first 4 odd natural numbers.
