You need at least two numbers to find a GCF.
For the values: 102, 34 the GCF is: 34
The GCF is 10.
The GCF is 6.
The GCF is 2.
The GCF is 4.
The GCF is 15.
Because the GCF of 31 and 33 is 1.
32 = 2^5 35 = 5 x 7 The GCF is 1.
If the GCF of the numerator and denominator is 1, the fraction is in its simplest form.
To answer the question two or more numbers are needed to find their GCF and LCM
The GCF of the numbers 24 and 4 would be 4. This is taught in math.
