Here's a simple observation to get you started. If you notice that both numbers are even, then divide by 2. This will give you 3 and 12 left over here. Noy you cant divide both by 2, so let's try 3. Success, leaving you with 1 and 4 respectively. So now you divided by a 2 and a 3, so multiply these to get your GCF, i.e. 2x3 is 6
The GCF is 6.
The GCF is 6.
The GCF is 6.
The GCF is... 12
The GCF is 6.
The GCF is 6.
The GCF is 6.
The GCF of 24, 30, and 42 is 6.The GCF is 6.
The GCF is 6.
what is the gcf of 24 and 54 is : 6
The GCF of 54, 36 and 24 is 6. The GCF of 5436 and 24 is 12.
The GCF is 6.
