# What is the GCF of 11, 12, 13, 14, 15, 16, 17 & 18? getcalc.com's HCF or GCF calculator & step by step work to find what is GCF of 11, 12, 13, 14, 15, 16, 17 and 18.

GCF(11, 12, 13, 14, 15, 16, 17, 18) = 1

The Greatest or Highest Common Factor 1 divides each one of the integer of this group. By using this GCF calculator & the work with steps, grade school students, teachers or parents can verify the results or the workout for HCF of 11, 12, 13, 14, 15, 16, 17 & 18.

## How to find HCF(11, 12, 13, 14, 15, 16, 17, 18)?

The below is the step by step work for how to find what is the GCF of group of numbers or integers 11, 12, 13, 14, 15, 16, 17 & 18.
Problem & Workout :
step 1 Address the method, input parameters & values
Integers: 11, 12, 13, 14, 15, 16, 17, 18
find gcf (11, 12, 13, . . . . , 18) = ?

step 2 Find the prime factors of all integers of the group
11 = 11
12 = 2 x 2 x 3
13 = 13
14 = 2 x 7
15 = 3 x 5
16 = 2 x 2 x 2 x 2
17 = 17
18 = 2 x 3 x 3

step 3There is no common factors between the integers, therefore the GCF (11, 12, 13, 14, 15, 16, 17 & 18) is equal to 1.
GCF(11, 12, 13, 14, 15, 16, 17, 18) = 1
