Prime numbers are those numbers which have exactly two factors, i.e. 1 and the number itself. Every prime number is an odd number except number 2. Complete step by step solution: Integers which are not divisible by 2 are called odd numbers. E.g. 1, 3, 5, 7 etc.
The integers which are not divisible by 2 are called odd numbers, e.g 1, 3, 5, 7 etc.
Divisibility means that a number goes evenly (with no remainder) into a number. For example, 2 goes evenly into 34 so 34 is divisible by 2. But 3 would leave us with a remainder, so 34 is not divisible by 3.
A number is divisible by 8 if its last three digits are divisible by 8. For example, 880 and 905,256 are divisible by 8 but 74,513 is not divisible by 8. To check divisibility by 8, divide the last three digits of the number by 8. If the result is a whole number, then the original number is divisible by 8.
Divisibility Rule of 2
Every even number is divisible by 2. That is, any number that ends with 2, 4, 6, 8, or 0 will give 0 as the remainder when divided by 2.
The divisibility rule of 4 helps to find out whether a number is divided by 4 or not without performing the division. The first four whole numbers that are divisible by 4 are 0, 4, 8, 12, and 16. All these are the multiples of 4 and every multiple of 4 is completely divisible by 4.
Only even numbers are divisible by 2.
Hence, an integer which is divisible by 2 is called an even number.
A number which is not divisible by “2” is called an odd number. An odd number always ends in 1, 3, 5, 7, or 9. Examples of odd numbers: 51 , − 543 , 8765 , − 97 , 9 , etc. An odd number is always 1 more than (or 1 less than) an even number.
