# Paper squares

The paper rectangle measuring 69 cm and 46 cm should be cut into as many squares as possible. Calculate the lengths of squares and their number.

Result

a =  23 cm
n =  6

#### Solution:

$69 = 3 \cdot 23 \\ 46 = 2 \cdot 23 \\ \text{GCD}(69, 46) = 23 = 23\\ \ \\ a = 23 \ \text{ cm }$
$n = 69\cdot 46/a^2 = 6$
