what is the GCF or greatest common factor of 18,27,30
(2*3^2, 3^3, 2*3*5) = 3
3 is the only factor common to all three numbers.
To find the greatest common factor (GCF) of 18, 27, and 30, you can follow these steps:
Step 1: Find the factors of each number.
The factors of 18 are 1, 2, 3, 6, 9, and 18.
The factors of 27 are 1, 3, 9, and 27.
The factors of 30 are 1, 2, 3, 5, 6, 10, 15, and 30.
Step 2: Identify the common factors.
The common factors of 18, 27, and 30 are 1, 3, and 9.
Step 3: Determine the greatest common factor (GCF).
The greatest common factor (GCF) is the largest number that divides evenly into all the given numbers. In this case, the GCF is 9 because it is the largest number that is a factor of 18, 27, and 30.
Therefore, the GCF of 18, 27, and 30 is 9.
