Five is a Prime number because it only has two factors: 5 and 1. Eight has four factors: 1, 2, 4, and 8.
A prime number is only evenly divisible by 1 and itself.
So 5 is a prime number. This is because it is only evenly divisible by (i.e. has factors of) 1 & 5.
8 is not a prime number. It has factors of 1,2,4 & 8.
The prime numbers that are less that 8 are 1, 2, 3, 5, and 7.
The prime numbers from 1 to 8 are 2, 3, 5 and 7.
no, not all prime numbers are closed under addition. why? because, when you add 2 prime numbers you will not always get a prime number. example: 5+3= 8 5 and 3 are prime numbers but their sum is 8 which is a composite number..
5 and 3 are two prime numbers which on adding give 8.
They are: 5+3 = 8
The prime numbers (factors) of 75 are: 3 and 5
There are 5 prime numbers between 8 and 28: 11 13 17 19 23
They are both prime numbers and 13-5 = 8 which is a composite number
Two numbers: 5 and 7 :)
If you mean the 1st 8 prime numbers then they are:- 2+3+5+7+11+13+17+19 = 77
There are 8 prime numbers from 5 to 30 (including the boundaries):5, 7, 11, 13, 17, 19, 23 and 29
Prime numbers are: 2 3 5 7 Composite numbers are: 4 6 8 9 10 So the ratio is: 4 to 5
