That's one of them.
The greatest common factor is 18.
GCF(36, 54, 72) = 18.
The Greatest Common Factor of 18, 36, and 72 is 18. Since 18 is a factor of 36 and 72, it is automatically the GCF.
It is 18
It is: 18
18
Since 36 is a factor of 72, it is automatically the GCF.
The GCF is 18.
The highest common factor of 36 and 72 is 36
The least common factor of any set of integers is 1.
The GCF is 6.
The mistake is that there is a greater common factor than 18. It's 36. 36 divides 36 evenly. 36 divides 72 evenly.
