The positive integer with only one factor is 1.
A factor of a integer is an integer that divides the second integer into a third integer exactly; i.e. A is a factor of B if B/A is exactly C, where all of A, B and C are integers. A prime factor is a factor as above, but is also a prime number. This means that the only factors of that factor are one and the number itself; i.e. A is a prime factor of B if B/A is exactly C andthe only factors of A are 1 and A.
No, 30 is not prime.
The prime factors of 20 are: 2 and 5.
Not a lot of room between 29 and 30. Prime factorization is the expression of a positive composite integer as the product of its prime factors. 30 has three prime factors. 2 x 3 x 5 is the prime factorization of 30.
No. Most integers aren't prime.
No. The number 30 is composite and so it cannot be a prime factor.
No on both counts. 4 is not prime and 4 is not a factor of 30.
The largest prime factor of 30 is 5 and its other prime factors are 2 and 3
Thanks to the fundamental theorem of arithmetic, there can be only one prime factorisation (leaving aside the factor 1), for ANY integer. As a result, there is only one prime factorisation of 30 and so nothing for it to be different from!
4890 163 is a prime number, so any integer (not negative or 0) will have only 1 as the common factor, hence it is also the GCF of 163 and 30.
8 is not a prime factor of 30. The prime factorization of 30 is 2x3x5.
