no. 3 and 11 are prime numbers. 12 is not a prime number as it can be divided by other things apart from itself and one. these other numbers are 3, 4, 6 and 2.
no all even numbers apart from 2 are not prime numbers :)
Yes. Apart from 2, all prime numbers are odd.
No - co-prime numbers are pairs of numbers which share no positive integer factors apart from 1. Twin prime numbers are a pair of prime numbers with a difference of 2.
Apart from 2 all even numbers are composite numbers because they have more than two factors.
A prime number can be multiplied by any other numbers because all whole numbers are the product of prime numbers.

No, there are no other even prime numbers. And an odd number + or - 3 is always even Ward
No. Numbers and luck have nothing to do with one another apart from superstitious belief.

Prime numbers have two factors. All square numbers (other than 1) have more than that.
Yes. Apart from 2, all prime numbers are odd.
no even numbers (apart from 2) are not prime 919 and 929 are prime

Prime numbers are those numbers which are only divisible by one and itself. For eg 2,3,5,7 ....
812 !!! You inspect the number; If it is an EVEN number it will divide by '2' If it ends in '5' or '0' it will divide by '5' If the digits sum to '9' , then it will divide by '9' Without any of the above, try dividing by either '3' or '7'. If none of the above work, keep trying by dividing by prime numbers; 11,13,17,19,23,29, etc., For 812 . It is an even number so it will divide by '2' It does not end in '5' or '0' so will NOT divide by '5' Its digits 8+1+2 = 11 Do not sum to '9' so will NOT divide by '9'. So 2)812 = 406 2)406 = 203 '203' is an ODD number so will not divide by '2' . Since it does not end in '5' ot will not divide by '5' . It digits do NOT sum to '9' so will not divide by '9'. So try '3' 3)203 = 67 remainder '2' Does not divide by '3' So try '7' 7)203 = 29 So there you have it . 812 breaks down to 2,2,7,& 29. the factors. When multiplied together 2 x 2 x 7 x 29 = 812 or 4x7 x 29 = 812 or 28 xx 29 = 812
Prime numbers are numbers only divisible by one and itself.i.e. it has no factors apart from 1 and itself.
