Numbers divisible by 1 & number itself are called prime numbers. These numbers also have the property to be odd numbers.

It means write down three pairs of numbers that are relatively prime like 4 and 9, 5 and 6, 13 and 25
A number as a product of prime numbers would be "x".
231 = 3 x 7 x 11

Prime factorization of 27 = 3x3x3
That's called the prime factorization.
You can't write that as the sum of two prime numbers. Note: Goldbach's Conjecture (for expressing numbers as the sum of two prime numbers) applies to EVEN numbers.
