2 and 5
Yes. The only time this occurs is right at the start of the list of primes: 2, 3.
There are only 2 primes in 80: 2 and 5.
The longest string of consecutive numbers that are primes is two digits long, consisting of 2 and 3 only. There are no other consecutive numbers that are primes because no even numbers greater than 2 are primes.
(24) = 2 * (12) = 2 * (6) = 2 * 3(both primes, end)primes then : 2,2,2,3
no primes other than two are even numbers. this is simply because any number larger then 2 can always be divided by two and itself while 2 can only be divided by 2 and 2 is itself. hope this was helpful
All prime numbers greater than 2 are odd numbers. For an odd prime to be written as the sum of two primes, one of the primes must be 2 because two odd primes will produce an even sum. 11 cannot be written as the sum of two primes. 13 = 2 + 11. 17 cannot be written as the sum of two primes. 19 = 2 + 17.
It is not. Of the infinitely many primes only one (the number 2) is even, the rest are all odd. The sum of any two primes other than 2 is even and therefore not a prime. If one of the primes in the sum is 2 then the sum is a prime only if the other is the lower of a pair of twin primes. So, while it is possible, it is certainly more likely that the sum is a composite.
2 and 3 are the only consecutive primes.
2 + 3 = 5 7 - 2 = 5 The number is 5.
There are infinitely many twin primes. One example is 5 and 7.
The numbers, 2 and 5, are co-primes because they both have just two factors, 1 and themselves.
