the prime factorization
A factor free is a diagram showing the prime factorization of a number.
The prime factorization of 81 is 3x3x3x3 or 34 in exponential form.
The prime factorization of 81 is 3^4, also written 3x3x3x3.
81 is not prime. Its prime factorization is 3x3x3x3.
81 = 3^4 so 3 is a prime factor.
The ladder diagram of 64 is a visual representation of decomposing the number 64 into its prime factors, which are 2x2x2x2x2x2. It is commonly used in mathematics to show the prime factorization of a number.
The prime factorization of 81 is: 3 X 3 X 3 X 3
The prime number is the prime factorization. For example, the prime factorization of the prime number 3 is 3. Get it?
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.
421 is a prime number so it does not have prime factorization.
When all the factors are prime numbers, that's a prime factorization.
91 cannot be in the prime factorization of any number because it is not a prime number itself.
