You can use Euclid's algorithm to calculate the gcf of two of the numbers - then use Euclid's algorithm again with the result and the third number.Or you can factor all the numbers into prime factors, and check which prime factors occur in all three numbers.
The GCF is 12.
The GCF is 12.
12
The GCF is: 36
The highest common factor of 504 and 336 is 168
Since 84 is a factor of 504, it is automatically the GCF.
The GCF is 72.
The GCF is 24.
The GCF is 84.
Since 24 is a factor of 336, it is automatically the GCF.
The greatest common factor between 504 and 336 is 168. You would find this by listing all the factors of 504 and 336 and choosing the highest one that would divide them evenly with no remainders.
The GCF is 48.
