Explanation:
To find the GCF of two numbers you can proceed as follows:
-
Divide the larger number by the smaller to give a quotient and remainder.
-
If the remainder is zero then the smaller number is the GCF.
-
Otherwise repeat with the smaller number and the remainder.
In our example:
#245/175 = 1# with remainder#70#
#175/70 = 2# with remainder#35#
#70/35 = 2# with remainder#0#
So the GCF is
