Oh, dude, "relatively prime" just means two numbers have no common factors other than 1. So, numbers that are relatively prime with 18 are ones that don't share any factors with 18 besides 1. In this case, numbers like 1, 5, 7, 11, 13, 17, and so on are relatively prime with 18. It's like 18 is at a party, and these numbers are the cool kids who don't have any drama with it.
The prime numbers (factors) of 18 are: 2 and 3
There are two pairs of prime numbers that express 18 as the sum of two prime numbers: 7 + 11 = 18 and 5 + 13 = 18.
Prime numbers are such number which are only divisible by 1 and by itself only..{1,2,3,5,7,11,13,17}
No, neither 12 nor 18 are prime numbers. A prime number is a number greater than 1 that can only be divided by 1 and itself. Both 12 and 18 can be divided by numbers other than 1 and themselves, so they are not prime.
The prime numbers from 1 to 18 are 2, 3, 5, 7, 11, 13, and 17.
The prime numbers between 1 and 18 are: 2 3 5 7 11 13 17.
Oh honey, let me break it down for you. The prime numbers between 18 and 28 are 19 and 23. Don't waste your time looking for any others in that range, those two are the cream of the crop. Math doesn't have to be complicated, just like a good slice of pie - simple and satisfying.
