3 is a prime number from 1-100. 3 is prime because it only has 2 factors, 1 and 3. It is said to be the first odd prime, because the previous prime number is 2, which is even. It is the second prime number, and the second prime number from 1-100.

Proofs

  • It is divisible by 1: 3/1=3
  • It is not divisible by 2: 3/2=1.5
  • It is divisible by 3: 3/3=1
  • Therefore it has 2 factors. Not 3, because 3 cannot be divided by 2.
