It is composite because 189=3x3x3x7
No, it is composite.
3 x 3 x 3 x 7 = 189
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.
The prime factorisation (not fractional!) of 189 is:189 = 3*3*3*7The prime factorisation (not fractional!) of 189 is:189 = 3*3*3*7The prime factorisation (not fractional!) of 189 is:189 = 3*3*3*7The prime factorisation (not fractional!) of 189 is:189 = 3*3*3*7
No. 189 is not prime because it is divisible by 9.
189 is a composite number because it has factors other than 1 and itself. It is not a prime number.The 8 factors of 189 are 1, 3, 7, 9, 21, 27, 63, and 189.The factor pairs of 189 are 1 x 189, 3 x 63, 7 x 27, and 9 x 21.The proper factors of 189 are 1, 3, 7, 9, 21, 27, and 63 or,if the definition you are using excludes 1, they are 3, 7, 9, 21, 27, and 63.The prime factors of 189 are 3, 3, 3, and 7. Note: There is repetition of these factors, so if the prime factors are being listed instead of the prime factorization, usually only the distinct prime factors are listed.The distinct prime factors of 189 are 3 and 7.The prime factorization of 189 is 3 x 3 x 3 x 7 or, in exponential form, 33 x 7.33 x 7 = 189.
