No. The prime factorization of 256 is 2*2*2*2*2*2*2*2 or 2^8. 4 is not prime.
the prime factorization of 32 is 2x2x2x2x2 and the factor tree is 32 8 4 2x4 2x2 2x2
No, 3x5x4 is not a prime factorization of 60. A prime factorization of 60 would consist of only prime numbers. The prime factorization of 60 is 2x2x3x5.
Because 2 is a prime number. 2 x 2 is the prime factorization of 4. 2 x 2 x 2 is the prime factorization of 8. 2 x 2 x 2 x 2 is the prime factorization of 16, and so on.
Prime FactorizationA factorization is prime when all the factors are prime numbers (those which only have itself and 1 as factors).For example,2 X 4 and 2 X 2 X 2 are both factorizations of 8. Only 2 X 2 X 2 is a prime factorization because 2 X 4 includes the composite number 4.
