Solution : 1 and the number itself.
Take a composite number 9
prime factorisation of 9
9=3×3
But the factors of 9=1,3,9
so, 1 and the number itself ,here, 9 will not included in the prime factorisation of 9 (composite number)
Question 3
Which factors are not included in the prime factorization of a composite number?
Which factors are not included in the prime factorization of acomposite number?
