They are: 1 and 11 which is a prime number

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!

To find a prime factor of a number, divide by 2 and see if you get no remainder. Then divide by 3, 4, 5, and so on, until one of the numbers you try gets you no remainder. If no such numbers work below the number you chose, it is prime. In the case of the number 9, 2 does not go into 9, but 3 does.

no 7 is though. 1 2 can divide 1 divides by anything from 1-the highest number. i think 2 is a prime number i am not sure but 3,5,7,11,13,17,19 and more are prime numbers. Well this is a diffrent person and they are all prime numbers.

Not Prime32 is not a prime number. In addition to 1 and 32, 2 and some other numbers will divide into it evenly. In order to be prime, a number must be divisible only by 1 and itself. Because all even numbers are divisible by 2, all even numbers except 2 are composite numbers.32 is NOT a prime number.
