Answer» Composite number is a number who have multiple more than one for example 4,6,8 while the numbers which have only the factor of 1 and the number itself are known as prime number for example 2,3,7,23 Please like ,share and subscribe my video on YouTube.https://youtu.be/crGyWC-oxjc Prime no. r those numbers that hv only 2 factor that is one and the number itself.e.g the number 2 is a prime number because it have only 2 factor that is 1 and 2 .Also let 3 is a prime number because it has only 2 factor that is one and the number itself.The factor of three are 1,3.Now,We can say that any number that have only two factor is known as prime number.And composite number are just opposite of prime number.*Composite number are the number that have more than two factor.means any number which have 2+ factor,those number will be known as composite number.E.g 8 is a composite number because it is a factor of 1,2,4,8.Now it can be said that 8 is a composite number as it have more than 2 factor.Thanks,hope u understand. prime no. - prime numbers are those numbers which have ony 2 factors , first factor is 1 and the other factore is the number itself .Composite no. - all the numbers having factors more than 2 ( i.e. 1 and the number its self ) - smallest prime number is 2 - smallest composite number is 4 - 1 is neither prime nor composite - many times question comes that find hcf of smallest prime and smallest composite number than people find HCF of 1 and 4 because they think 1 is smallest prime number . - Always remember 1 is neither prime nor composite. - I am your senior 2020 batch , if you want my hand written notes for every subject , u can mail me at.
