The definition of a Prime number is a number that can only be divided by 1 and itself. Prime numbers can not be divided by anything but 1.
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.
The prime numbers are: 5 and 43
The prime numbers that divide 69 evenly are 3 and 23.
The only way to know if a number is prime or not is to try and divide it by every number and if non of them work then it is a prime number
if divide the prime numbers by the compositenumber it will give you a greater number that is either a prime number or composite.
1, 61 (61 is a prime number).
They are: 1 and 11 which is a prime number
The only prime number divisible by 7 is 7. There are no prime numbers divisible by 8.
To prove that 61 is a prime number.
No, never.
1 and 41 are the only numbers that divide into 41. Because of that, 41 is called a prime number.
Prime factors of numbers are small numbers that the bigger (original) number can divide by. The prime factors have to be prime. This means they only have two factors, itself and one.
If there are no numbers to divide - not even 1 - then you have made a mistake.
