Greater than one, numbers are either composite or prime, never both.
The list is far too long to list here (millions of them); a search on "list of prime numbers" can quickly give you the desired prime numbers.
Actually 2x2x5x7x11 is a prime factorization and on multiplying these numbers we get 1540. Prime factorization of a number is the prime numbers which on multiplying together give that number.
Six twos.
Okay. Give us a pair of numbers.
There 4 pairs of primes that can give a sum 40 in addition. They are (3,37), (11,29), (17,23),(19,21).
The prime numbers 2 and 3.
To find the pairs of whole numbers that multiply to give 99, we need to determine its factors. The factors of 99 are 1, 3, 9, 11, 33, and 99. The pairs of whole numbers that multiply to 99 are (1, 99), (3, 33), and (9, 11), resulting in a total of 3 distinct pairs.
18 prime numbers
Greater than one, numbers are either composite or prime, never both.
Square numbers can't be prime. They have too many factors.
The list is far too long to list here (millions of them); a search on "list of prime numbers" can quickly give you the desired prime numbers.
2 and 3
The prime factorization for 18 is: 2 x 9 2 x 3 x 3, so the two prime numbers that give you 18 are 2 and 3.
Two numbers, like 4 and 9, are considered co-prime if their GCF is 1.
5 and 3 are two prime numbers which on adding give 8.
Prime numbers have only two factors which are themselves and one such as 23 and 29
