Every integer has a unique set of factors. Multiples of numbers contain their factor's factors as well as their own.

Here are pairs of numbers whose prime factorizations use the same prime factors:
4 = 22
32 = 25
6 = 2 x 3
24 = 23 x 3
5 = 5
625 = 54
21 = 3 x 7
63 = 32 x 7
30 = 2 x 3 x 5
180 = 22 x 32 x 5
All prime numbers have two factors: one and itself. (For example, the factors of 11 are 1 and 11.)
Example: 36 and 175
2 x 2 x 3 x 3 = 36
5 x 5 x 7 = 175
There are no common prime factors. The GCF is 1. By definition, that makes them relatively prime.
The prime factorization of a number uses only primes. Ex: The prime factorization of 12 is not 6 x 2, and not 4 x 3, because 6 and 4 are not prime numbers. The prime factorization is 2 x 2 x 3. Their product is 12 and all factors are prime numbers. To get a prime factorization you are usually taught to factor through division by small prime numbers, sometimes you must use the same number more than once as in the example of 12 above 2 was used twice. Ex: find the prime factorization of 18. The smallest prime is 2... divide by 2 18 / 2 = 9 .... for the next step divide 9 by a prime 9 / 3 = 3 ... this is a prme ... it is also a factor so the prime factorization is 18 = 2x3x3 Ex. find the prime factorization of 35. 35 cannot be divided by 2, or 3, so use 5 first 35 / 5 = 7 .... since 7 is a prime we are finished. The prime factorization of 35 is 35 = 5 x 7 Some teachers teach this using a "factor tree" .. I can't type one of those on a computer.
There are a lot of possibilities. The seventh square number is 49. 5 times 5 times any other prime number will be greater than 49. 5 times any pair of prime numbers seven or greater will also satisfy the conditions.
19*5 this answer is also the same in exponent form.The prime factorization of 95 is 5*19.5 x 19 = 95
It's not, because all the factors of 20 aren't prime.
Usually, but not necessarily and not if they're prime. All prime numbers have the same number of factors.
