An even number can be divided by 2 evenly. An odd number will have a remainder of 1 when divided by 2. 144 is an even number.

Yes.

Express the number in its prime factorisation in power format. The number of factors of the number is the product of the powers each increased by 1. 144 = 2^4 × 2^2 → number of factors is (4+1) × (2+1) = 3×5 = 15; so 144 has an odd number of factors. As an even number times an even or odd number is even, the only way the product above can be odd is if every power increased by 1 is odd, that is only if every prime is to an even power. By using the laws of indices, this means the power of every prime can be divided by 2 and the whole prime factorisation so created raised to the power 2 which is squared, eg for 144: 2^4 × 3^2 = (2^2 ×3^1)². Thus for a number to have an odd number of factors it must be a perfect square. 144 is a perfect square (144 = 12²) therefore it has an odd number of factors. This result that only perfect squares have an odd number of factors can also be seen by looking at the factor pairs of a number: the factors of a number can be paired up so that when the numbers of a pair are multiplied together they get the original number. If there is an odd number of factors then after the pairing there will be one factor left unpaired, but as it is a factor of the original number it must have a pair. Therefore the only pair possible is with itself, ie the number is this factor squared and the number is a perfect square. for example: for 144, the factors are: {1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, 144} which can be paired as: {1, 144}, {2, 72}, {3, 48}, {4, 36}, {6, 24}, {8, 18}, {9, 16} leaving the factor 12 unpaired, so it must pair with itself as {12, 12} which means 144 = 12² and is a perfect square (with an odd number of factors).

The three greatest whole numbers less than 200 that each have an odd number of factors are 144, 169 and 196.

196, 169, 144

144, 121 and 100

3764. The rest are perfect squares.

odd

An odd number minus an odd number is an even number.

when an odd number is subtracted from an odd number the answer is an even number.

you get an odd number

These are the products of the given odd number and any odd number.

An odd number times an odd number is an odd number no matter which 2 odds you multiply.

an odd numberSubtracting an odd number from an even number will always result in an odd number.

144 is a square number, not a triangular number.

The sum of an odd number and an even number will always give an odd number. Ex: 2 + 5 = 7

The difference of an odd number and an even number is an odd number.

No. As both negative and positive numbers can be odd, there is no first odd number, and therefore no 100th odd number. The 100th odd positive number is 199.

That happens because 5 is an odd number. An odd number times an odd number will give you an odd product; an odd number times an even number will give you an even product. The same happens for the multiples of any other odd number.

What is the 12 square number

Because the second number from an odd number is odd, and every other number is an odd number. In fact, if you add or subtract an even number with any number, the result keeps the same parity as the other number. So an odd number minus an even number is odd, while an even number minus and even number is even.

Yes, 144 is an even number.

No because 144 is a square number

yes it is an odd number because the last number in the entire number is an odd number
