How do you find the factor for 189?
First, find the prime factorization. Use a factor tree. 189 63,3 21,3,3 7,3,3,3 All the other factors will be combinations of these. There are eight altogether. You know that 1, 3 and 7 are factors. The rules of divisibility tells you that 9 is as well. Dividing them into 189 gives you the rest. 1, 3, 7, 9, 21, 27, 63, 189
What are the factors and prime factors of 189 on the factor tree?
The 8 factors of 189 are 1, 3, 7, 9, 21, 27, 63, and 189. 3 and 7 are prime.
How do you make a factor tree for 189?
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.
