The only prime factor of 27 is: 3.
1,3,9 and27
You have to first find all the factors of each number. Then find the greatest one they have in common. Lets do 27 and 81factors of 27 - 1, 3, 9, 27factors of 81 - 1, 3, 9, 27, 81the GCF is 27
The greatest common factor (GCF) of 27 and 189 is 27. To find the GCF, you can list the factors of each number and find the largest number that both 27 and 189 share. The factors of 27 are 1, 3, 9, and 27, while the factors of 189 are 1, 3, 7, 9, 21, 27, 63, and 189. The largest number that appears in both lists is 27, making it the GCF.
81 has these five factors: 1 3 9 27 81.
All Factors of 81:1, 3, 9, 27, 81
The factors of 27 are 1, 3, 9, and 27.
Find out all the factors and then find the greatest common factor (gcf)...........very easy
27 has four factors.
The factors of 27 are: 1, 3, 9, 27.
Factors of 27: 1, 3, 9, 27
You find their factors and compare them to see which ones are in common. The factors of 27 are 1, 3, 9 and 27. The factors of 77 are 1, 7, 11 and 77. The only common factor they have is 1. Therefore they are relatively prime.
