3rd level; Prime numbers Prime numbers from 1 - 100. Prime numbers are numbers that can only be divided by themselves and one. If a number is a multiple of any other number, then it is not a prime.

Therefore, 29 is a prime number. Prime Numbers 1 to 100. Prime Numbers from 1 to 10: 2, 3, 5, 7: Prime Numbers from 11 to 20: 11, 13, 17, 19: Prime Numbers from 21 to 30: 23, 29: ...

Prime numbers also must be greater than 1. For example, 3 is a prime number, because 3 cannot be divided evenly by any number except for 1 and 3. However, 6 is not a prime number, because it can ...

There are 25 prime numbers between 1 and 100. A prime number is a whole number greater than 1 that has only two divisors: 1 and itself. The prime numbers between 1 and 100 are 2, 3, 5, 7, 11, 13 ...

41 is the prime number. It is not even and doesn't end in 0 or 5. It isn't divisble by any other number. So, it only has two factors: 1 and 41. 98 is a composite number.. You can work this out ...

Prime numbers are quite extraordinary. They're like "special snowflakes" - unique in the way that they don't have any other positive divisors other than the number 1 and the prime number itself.

A prime number p has exactly two distinct positive divisors, 1 and p itself. If p is a prime number and divides a product ab, then p must divide at least one of a or b.

If you do this with all numbers from 2 to 100, only prime numbers will remain. Sieving multiples of 2, 3, 5 and 7 leaves only the primes between 1 and 100. Courtesy of M.H. Weissman.

A major milestone was reached in 2005, when Goldston and two colleagues showed that there is an infinite number of prime pairs that differ by no more than 16 (ref. 1). But there was a catch.
