The 8 factors of 189 are 1, 3, 7, 9, 21, 27, 63, and 189. 3 and 7 are prime.

7 is a prime factor of 189, because 7 X 27 = 189.

The greatest common factor of 81 and 189 is 27.

The Greatest Common Factor of 189 and 449 is 1.

Since 27 is a factor of 189, it is automatically the GCF.

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.
