Suppose you are given a number n and are told that 1 and the number n divide into n Does that mean n is prime?
No. All integers are divisible by 1 and themselves. Prime numbers are only divisible by 1 and themselves. Since you were not told that only 1 and n divide into n, you do not know if it is prime. Also, if n = 1, it is neither a Prime number nor a composite number.

What prime number can divide 27 and 36?
The prime number 3 can divide 27 and 36.
How do you use your calculator to find prime numbers?
I suppose the calculator has no prime number-related function Suppose you want to know if x is a prime If x is not a prime then the greatest factor that can be in x is sqrt(x) So you can try to divide x by all prime numbers between 2 and sqrt(x), if none of this calculation returns an integer then x is prime.
What is the smallest prime number that will divide 147 evenly?
The smallest prime number that will divide 147 evenly is three.
What is the difference between prime numbers and prime factor?
Prime numbers are integers greater than 1 that have no positive divisors other than 1 and themselves. Prime factors, on the other hand, are prime numbers that divide a given integer without leaving a remainder. In other words, prime factors are the prime numbers that, when multiplied together, result in the original integer. For example, the number 12 has prime factors of 2 and 3, as 2 * 2 * 3 = 12.
With a given big integer number which is the product of two prime numbers how do you find them?
First write a program to generate the prime number. After one prime number was generated, divide the big int number by the prime number. If the remainder is zero then quotient is the second prime number ( also it is important to check whether the quotient is prime number or not because sometimes you will get wrong answer). Repeat the process until you get the result.
How do you check if a large number is prime or a composite number?
You divide the number by 2. If the number is able to divide WITHOUT a remainder, then it is a prime number. If you divide a number by 1, you will get the same number. That is not a prime number.
Is 167 a composite number?
== == No, it's a prime - because none of the primes less than 13 will divide the given number.
What prime number can divide 27 and 36?
The prime number 3 can divide 27 and 36.
How many rectangles can you build with a prime number square tiles?
Given P = Prime number then you can build (P-1)/2 number of rectangles given any prime number. All prime numbers are odd and you would need two squares to make a rectangle. Given that you need two squares to build a rectangle, you divide your prime number by two to get the number of "pairs" of squares and thus the number of rectangles you can build. Since the number 2 does not divide evenly into an odd number - all prime numbers are odd - then you either subtract one from the prime number before dividing or discard the remainder if you choose not to subtract one before dividing.
How do you find a fraction of a prime number?
Divide the prime number.

What are prime numbers between 80 and 90?
There are only 9 numbers between 80 and 90 - so lets look at them all Remember we only need to find 1 number that will divide the number except for 1 and itself for it to be NON-PRIME. 81 - 3 will of course divide this number - so not prime. 82 - 2 will of course divide this number - so not prime. 83 - PRIME!!! 84 - 3 will of course divide this number - so not prime. 85 - 5 will of course divide this number - so not prime. 86 - 2 will of course divide this number - so not prime. 87 - 3 will of course divide this number - so not prime. 88 - 2 will of course divide this number - so not prime. 89 - PRIME!!! So, the only numbers between 80 and 90 that are primes are 83 and 89!
Why it is that number 2 is the smallest number in Prime?
It isn't 1 is. 1 is always the smallest. Can you divide 1 and get a whole number? No a prime number is something that you can divide into, yes you can divide it, making it a negative number, but not a whole number. * * * * * In fact, 1 is NOT a prime (nor a composite), so 2 IS the smallest prime.
