Prime factorisation of letters is not defined.
When all the factors are prime numbers, that's a prime factorization.
There is no need to do prime factorization as prime numbers are already prime.
Composite integers each have their own unique prime factorization. Since Y and W can be any number, we can't give a more specific answer.
That's the prime factorization.
The prime factorization of 238 is: 2 × 7 × 17
That's the prime factorization.
Prime factorization never includes a composite number. All numbers in prime factorization must be prime numbers.
When all of the factors are prime.
The prime factorization.
That's a prime factorization.
Prime factorization is when you find all the prime factors of a number.
The prime factorization of 70 is 2 x 5 x 7.
