The GCF is 1.
That only applies to integers. The GCF of 5 and 8 is 1.
The GCF is 8. 32/40 = 4/5
The GCF of 20 and 32 is 4, allowing you to simplify to 5/8
The GCF is 1.
The GCF of 5 and 8 is 1. The LCM is 40.
The greatest common factor of 8 and 11 (5+6) is 1.
The GCF is 1.
It is: 8
8/20 = 2/5 (You divide the numerator and the denominator by the GCF, which in this situation is 4)
The GCF of 2 and 5 is 1.
The GCF of 2 and 8 is 2. 2/8 = 1/4
The GCF of 4, 5, and 8 is 1. Since 4 and 5 are consecutive integers, their GCF is 1.
