GCD of 80 and 29 - GCD / GCF Calculator
Find the Greatest Common Divisor for any set of integers (2, 3 or more whole mumbers). Here is the answer to the questions like: GCD of 80 and 29 or What is the highest common factor (hcf) of 80 and 29?
To use the GCD / GCF / HCF Calculator below just enter a set of numbers separated by commas (,).
How to find the Greatest Common Divisor
The first step is to find all divisors of each number. For instance, let us find the gcf(80, 29).
In this case we have:
- The factors of 80 (all the whole numbers that can divide the number without a remainder) are 1, 2, 4, 5, 8, 10, 16, 20, 40 and 80;
- The factors of 29 are 1 and 29.
The second step is to analyse which are the common divisors. It is not difficult to see that the 'Greatest Common Factor' or 'Divisor' for 80 and 29 is 1. The GCF is the largest common positive integer that divides all the numbers (80, 29) without a remainder.
The GCF is also known as:
- Greatest common divisor (gcd)
- Highest common factor (hcf)
- Greatest common measure (gcm), or
- Highest common divisor
