Is 189 a prime or composite number?
189 is a composite. Some quick tests, which can be done in your head: Check if the number is even (2 is a factor). Ones place will have 0,2,4,6, or 8 if even. Multiple of 5 (5 is a factor): Ones digit is 0 or 5. Multiple of 3 or 9: Add up the digits in the number; if this sum is 3 or a multiple of 3, then the original number is a multiple of 3 (3 is a factor). Additionally, if this sum equals 9 or a multiple of 9, then 9 is a factor. This is the case for 189 : 1+8+9=18, which is a multiple of 9. Since we found a factor (in addition to 1 & the original number) then the number is composite and not prime.
