The prime numbers (factors) of 189 are: 3 and 7
The prime number (factor) of 289 is: 17
it is the factors of 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.
160 and 189 are relatively prime as they have no common factors other than 1.
7 is a prime factor of 189, because 7 X 27 = 189.
Neither 189 nor 1500 are prime factors.
Seven.
The 8 factors of 189 are 1, 3, 7, 9, 21, 27, 63, and 189. 3 and 7 are prime.
Prime factors of 189 are 33 and 7Prime factors of 231 are 3, 7, and 11HCF of 189 and 231 is 7
The factors of 189 are 1 3 7 9 21 27 63 189 So the largest factor is 189. However, 189 is not a proper factor, even though it is a factor. The largest proper factor is 63. Now 63 is not prime, since is is clearly divisible by 3. The largest prime factor is 7
The process of prime factorisation is one of repeated division by primes, while obtaining a quotient without a remainder, until the process yields a quotient of 1 3024 ÷ 2 = 1512 ................................. 2 is a prime factor of 3024 1512 ÷ 2 = 756 ................................... 2 is a prime factor of 3024 756 ÷ 2 = 378 ..................................... 2 is a prime factor of 3024 378 ÷ 2 = 189 ..................................... 2 is a prime factor of 3024 189 is not divisible by 2 189 ÷ 3 = 63 ....................................... 3 is a prime factor of 3024 63 ÷ 3 = 21 ......................................... 3 is a prime factor of 3024 21 ÷ 3 = 7 ........................................... 3 is a prime factor of 3024 7 is not divisible by 3 7 ÷ 7 = 1 ............................................. 7 is a prime factor of 3024 So the prime factors of 3024 are 2, 2, 2, 2, 3, 3, 3 and 7
189 = 3 x 3 x 3 x 7 = 33 x 7
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
First, find two numbers that when multiplied together equal 189. I can tell by looking at the number that it is divisible by 9. Any number whose digits add up to a number divisible by 9 is also divisible by 9. 1 + 8 + 9 = 18, which is divisible by 9. 189 ÷ 9 is 21. So, the top of our factor tree is: 189 9 x 21 Now, determine two pairs of numbers that when multiplied together, one pair will equal 9 and the other pair will equal 21. 9 = 3 x 3 and 21 = 7 x 3. So, now our factor tree is: 189 9 x 21 (3x3) x (7x3) You would continue doing this until you no more numbers can be factored. Since 3 and 7 are prime numbers, the factor tree is finished. The factor tree shows that the prime factorization of 189 is 3 x 3 x 3 x 7 or 33 x 7.
No. 189 is not prime because it is divisible by 9.
The factors of 189 are: 1 3 7 9 21 27 63 189The prime factors are: 3, 7The prime factorization is: 3 x 3 x 3 x 7
