In the previous post we have discussed about Convert Percent to Fraction and In today's session we are going to discuss about Is 1 a Prime Number. Let us first learn what are prime numbers? The numbers which have only two factors, 1 and itself are called prime numbers. Now another question arises that is 1 a prime number?
If we start looking at the series of the natural numbers and separate the series of the prime and the composite numbers, we find that the number 2 has the factors 1 and 2, so it is a prime number. Next number we have is 3, which has the factors 3 and 1, thus 3 is also prime number. Moving on to 4, we say that factors of 4 are 1, 2 and 4. So 4 is a composite number. Similarly we go on checking the series of natural numbers and come to the conclusion that 2, 3, 5, 7, 11, 13, 17. . . . are the series of prime numbers and 4, 6, 8, 9, 10. . . are all composite. (know more about Prime number , here)
We also must know that 2 is the smallest prime number. Now what about the number 1? We say that the number 1 is neither a prime number nor a composite number. Yes we say that the number 1 has the factor 1 and itself (which is again 1). But it is a special number, which neither belong to the series of the prime numbers nor to the series of the composite numbers. So the answer to the question that is 1 a prime number is a big NO. Thus we say that 1 is a special number and it does not belong to the family of prime numbers.
To learn about what is a Polynomial, we can visit online math tutor and understand the concept of doing different mathematical operations on the polynomials. To know about the curriculum of math grade 10 for Gujarat board, we can visit the website of the board and collect the required information.
