what are prime numbers? Can anyone explain me with an example?

prime numbers are numbers having two factors 

Example: 2

It has 2 factors:- 1 and 2

PRIME NUMBERS ARE THOSE NUMBERS HAVING ONLY TWO FACTERS

 

EG:-2,5,7,11,13,17,19ETC

Prime nos are the nos which have only 2 factors i.e. 1 and the no itself. 

Examples are; 2,3,5,7,11,13,17,19,23,etc

Prime numbers are the numbers whose factors are 1 and the number itself. For suppose consider 2, it has factors as 1 and the number itself i.e., 2 but composite numbers are the numbers which have more than two factors ex 4 it has factors 1, 2 , 4 which is other than 1 nd the number itself. least prime number is 2 and 2 is also the least even prime number

prime numbers are numbers having two factors 

prime numbers are the ones whose factors are 1 and itself. They can have many multiple though. The no.s which do not have only two fators are called composite numbers. e.g. for prime numbers:2,3,13,17,5 etc. e.g. for composite no.s:4,9,18, 49 etc. 

extra tip: 2 is the only even prime number

Prime numbers are those kinds of numbers which are having their factors as 1 and the number itself.

 

For example, take the number 5. 

 

What all factors does it have?

They are 1, number itself, that is, 5.

 

So, a few examples of prime numbers are 2,3,5,7,11,13,17,19,23,29,31 and so on.

 

One more thing is that : 2 is the only even prime numbers. All other numbers are composite, that is, they have more than 2 factors. 

 

For example, 16. The factors of 16 are 1,2,4,8,16, so that sums up to a total of 5 factors.

 

Hope this answer helps.

a number having only two factors 1 and the nummber iitself like 3 5 7.

Dear student 

Prime numbers are those numbers which have only two factors i.e- 1 and itself

Eg:- 2,3,5,...............

Dear student .

prime numbers are those numbers which are divisible by 1 and by itself only . No other number can divide them .

For example , 2 is a prime number . It is divisible by 1 and 2 only .

similarly 5 is a prime number.
