Composite. A Prime number is defined as "a number not divisable by any integer other than itself and 1". It can be seen that 1575 can be divided by 5,15,25,75 and maybe more. None of these numbers are 1575 or 1 so the number is composite.
As a product of its prime factors: 3*3*5*5*7 = 1575
neither prime or composite
It is prime
It would be impossible to list them all, since numbers go on forever, but here are some of them: 2 - Prime 3 - Prime 4 - Composite 5 - Prime 6 - Composite 7 - Prime 8 - Composite 9 - Composite 10 - Composite 11 - Prime 12 - Composite 13 - Prime 14 - Composite 15 - Composite 16 - Composite 17 - Prime 18 - Composite 19 - Prime 20 - Composite 21 - Composite 22 - Composite 23 - Prime 24 - Composite 25 - Composite 26 - Composite 27 - Composite 28 - Composite 29 - Prime 30 - Composite 31 - Prime 32 - Composite 33 - Composite 34 - Composite 35 - Composite 36 - Composite 37 - Prime 38 - Composite 39 - Composite 40 - Composite 41 - Prime 42 - Composite 43 - Prime 44 - Composite 45 - Composite 46 - Composite 47 - Prime 48 - Composite 49 - Composite 50 - Composite
1575 = 3 * 3 * 5 * 5 * 73 x 3 x 5 x 5 x 7 = 1575
No, 1575 is not a prime number, because it can be divided by numbers other than 1 and itself. In particular without much thought you can see that it is divisible by 5.
As a product of its prime factors: 3*3*5*5*7 = 1575
1575 = 32 x 52 x 7
32*52*7 = 1575
neither prime or composite
