They all have two distinct factors.

If p, q and r are distinct primes and n=pxqxr then n will have 8 factors, all of which will be positive since prime numbers are all positive, which are: n(pqr), pq, pr, qr, p, q, r and 1. Here there were 3 distinct primes so the number of positive factors is 2^3. In general if you had p distinct primes then you would have 2^p positive factors.

Not two DISTINCT prime factors, no. For example, 64 = 2^6 only has prime factor 2. All even numbers which are not a power of 2 must have at least two distinct prime factors, however; one of them will, of course, be 2.

Yes, 12 has prime factors. The prime factors of 12 are 2, 2, and 3, so the distinct prime factors are 2 and 3. Almost all integers have prime factors. The integers without prime factors are -1, 0, and 1.

All numbers (except for 1 and 0) have prime factors. Sometimes the prime factors are repeated. The prime factorization of 216 is 2 x 2 x 2 x 3 x 3 x 3. The distinct prime factors of 216 are 2 and 3.

1 and 59. It is a prime number.

30, 42, 66, 78, 102, 105, 114, 138 all have exactly three distinct prime factors.

All numbers have factors. Some factors are prime numbers. These are prime factors. A factor string where all the factors are prime numbers is called a prime factorization.

The only number between 30 and 40 with distinct prime factors which add up to 12 is 35.

All odd numbers with one or two distinct prime factors are deficient. Since 3 and 7 are factors of 63, it must be deficient.

The prime factors are 2x2x2x13 All factors are 1,104,2,52,4,26,8,13

All non-zero numbers have factors. Some factors are prime numbers. Prime factors are factors that are prime numbers.

All numbers have factors. Some factors are prime numbers. These are known as prime factors.

All numbers have factors. Some factors are prime numbers. These are known as prime factors.

All the prime factors of 76 are 2 and 19.

All numbers have factors. The factors that are positive numbers are known as positive factors.

The prime factorization of 36 is 2 x 2 x 3 x 3, which totals 10 if you add them. The distinct prime factors of 36 are 2 and 3, which total (I'll let you fill that in) if you add them.

Distinct would mean they are all different, so take the 3 lowest primes and multiply them: 2*3*5 = 30

A prime numbers has no positive integer factors except itself and 1. The number 1 has only itself as a factor. The number 0 has no factors at all.

Prime factors are: 2,3,5,7,11,13,17,19.23,29,31,37,41,47,53,59,61,67,71,73,79,83,89,97

There are infinitely many prime factors.

Squares (or cubes or more) of prime numbers have one distinct prime factor, but if you're counting them individually, all composite numbers have at least two prime factors.

If it has two factors, it's prime. If it has more than two factors, it's composite.A prime number is a positive integer with two factors: one and the number itself.A composite number is a positive integer with more than two factors.

All numbers have factors. Some factors are prime numbers. These are called prime factors.
