1 is not a prime number either, it only has one factor.
The lowest prime number is 2, it is also the only even prime number.

1,2,3 are. 4 is divisable by 2, so it is not a prime number. Prime numbers are only divisable by themselves and 1.

no.
only 1, 2, and 3 are prime numbers.
prime numbers only have 2 and itself as factors.
following the definition...
1=1x1
2=2x1
3=3x1
4=1x4, 2x2
