# Which of the following number is not a perfect square 961?

No, 961 is not a perfect square. A perfect square is a number that both a square root and a square of a non-negative integer, so 961 does not qualify as a perfect square. To find a perfect square, we must find the square root of an integer, so 961 would not fit this criteria as its square root is 31.026 and is not an integer.

## What is the perfect square root of 961?

The perfect square root of 961 is 31. The perfect square root of any number is the number that when multiplied by itself will equal the original number. To find the perfect square root of any number, you must factor the original number into two numbers that when multiplied together will equal the original number.

For 961, the factors are 31 and 31, so the perfect square root is 31.

## Why is 961 a perfect square?

A perfect square is a number that can be written as a product of two equal-length factors. 961 is a perfect square because it can be written as 30 x 32, which is two equal-length factors. Additionally, 961 can also be written as an exact square root, which is equal to 31.

This means that the square root of 961 is an integer of equal length. The two factors of 961 make it a perfect square; this is what makes it different from other integers, like 960, which doesn’t have two factors of equal length.

## What is the square root of 961 by repeated subtraction?

The square root of 961 can be calculated by the repeated subtraction method. To do this, the number to be square rooted is divided by the largest possible even number, the result of which is again divided by the largest possible even number, and so on until the result is 1.

To find the square root of 961 using the repeated subtraction method, start by dividing it by 28, the largest possible even number:

961/28 = 34

Again, divide the result by 28:

34/28 = 1

Now, use the result 1 to calculate the answer:

28 x 1 = 28

So the square root of 961 is 28.

## What are all the factors of 961?

The factors of 961 include all of the integers that divide 961 without a remainder. These are 1, 3, 11, 27, 33, 93, 99, 109, 297, 363, 361, 961. It is important to note that when determining the factors of any number, the factors include both positive and negative (non-zero) numbers.

## What numbers can be divided 961?

961 can be divided by the following numbers: 1, 3, 17, 31, 51, 93, 961. All of those numbers are factors of 961.

## How do you find the perfect square?

Finding the perfect square of a number can be done by first understanding the definition of a perfect square. A perfect square is a number that is the result of multiplying an integer by itself. In other words, a perfect square is an integer that can be expressed as the product of two equal integers.

To find the perfect square of a given number, you can use one of two methods.

The first method is to use the “factorization” method. This involves finding the two equal factors that will multiply together to give you the desired perfect square. To do this, you list out all the factors of your number (the factors may be the same number, such as 2 x 2 or 4 x 4, or different numbers such as 3 x 4).

Once you have all the possible factors, you can add them together to get the perfect square.

The second method, called the “square root” method, involves taking the square root of your number to find the perfect square. The square root of a number is the number that, when multiplied by itself, will equal the number you are trying to find the perfect square of.

To use the square root method, you need to have an understanding of what the square root of any number is and how to calculate it. Once you have the square root of your number, you can multiply it by itself to get the perfect square.

Although it can take some practice to master either method, each has the same result: a perfect square of your desired number.

## Is 961 even or odd?

961 is an odd number. Any integer that can be divided evenly by two is an even number. Conversely, any integer that cannot be divided evenly by two is an odd number. 961 divided by two is not a whole number, thus 961 is an odd number.
