What is the two primes that end in 2 or 5?
2 and 5
Can two consecutive numbers both be primes?
Yes. The only time this occurs is right at the start of the list of primes: 2, 3.
How many primes are there in 80?
There are only 2 primes in 80: 2 and 5.
What is the longest number string that only consists of prime numbers?
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.
What is a the prime factorization of 24?
(24) = 2 * (12) = 2 * (6) = 2 * 3(both primes, end)primes then : 2,2,2,3
How many primes other than two are even numbers?
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
Is the sum of two prime numbers always a prime numer?
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.
How many of the prime numbers between 10 and 20 can be written as the sum of two primes?
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.
The prime numbers 2 and 3 are consecutive primes since one follows the other are there any of consecutive primes?
2 and 3 are the only consecutive primes.
What is the only prime that is the sum and diffence of two other primes?
2 + 3 = 5 7 - 2 = 5 The number is 5.
What are the two primes that differ from 2?
There are infinitely many twin primes. One example is 5 and 7.
Which set of numbers includes prime numbers only?
The set of primes would be one. The set of Mersenne primes is another. The set of all primes below 50 is another. And so on. A set which includes all primes, and only them, is the set of numbers having exactly 2 factors.
