The LCM is: 680The GCF is: 4
Gcf = 4 lcm = 560
8 and 80, respectively.
For 32 and 40: 1. The GCF is 8 2. The LCM is 160
20 is the GCF. The LCM is 40.
Gcf: 40 lcm: 600
The GCF of 5 and 8 is 1. The LCM is 40.
The GCF is 2. The LCM is 40.
GCD(40, 4900) = 20 LCM(40, 4900) = 9800
The greatest common factor of the numbers 16, 40 and 88 is 8.
