20. You can factor out a 10 from both, so the answer is 10 times the GCD of 8 and 1210. 1210 = 11 x 11 x 10 = 11 x 11 x 5 x 2 8 = 2 x 2 x 2 So the GCD of those is 2, meaning the GCD of 80 and 12100 is 20.
GCD(12, 40) = 4
The Greatest Common Divisor (GCD) for 40 16 is 8
Note that 20 exactly divides 40 because 40 / 20 = 2. Then, the GCD of 20 and 40 is 20.
12100
Since 20 divides 12100, 20 is the gcf of the two numbers.
lcm(40, 12100) = 24200
The LCM is 24200.
