A Prime number has only two factors which are itself and one whereas a composite number has more than two factors and 1 is not considered to be prime or composite because it has only one factor which is itself.
40 is simply a number. It does not and cannot explain prime factorisation!
In actual fact, the prime factorization of 42 is not 21 x 2, as 21 is not a prime number. The complete prime factorization of 42 is 2 x 3 x 7.
The prime number is the prime factorization. For example, the prime factorization of the prime number 3 is 3. Get it?
The most important concept is that, apart from their order, the prime factorisation of any number is unique. This is known as the Fundamental Theorem of Arithmetic.
53 is a prime number so there is no relevant prime factorization for it.
The only number with that prime factorization has to be 48.
When all the factors are prime numbers, that's a prime factorization.
421 is a prime number so it does not have prime factorization.
91 cannot be in the prime factorization of any number because it is not a prime number itself.
Yes. Any prime number greater than 100 has only itself in its prime factorization. Examples: The prime factorization of 101 is 101. The prime factorization of 109 is 109. The prime factorization of 127 is 127. The prime factorization of 311 is 311. The prime factorization of 691 is 691.
19 is a prime number, so it has no prime factorization.
