# PLOTS OF GCD, LCM, REMAINDER, AND QUOTIENT ```PLOTS OF GCD, LCM, REMAINDER, AND QUOTIENT
Below are 3D plots of the greatest common divisor, least common multiple, remainder, and integer quotient functions of nonnegative integers x and y. These plots were produced by Mathematica. For each function, two plots are shown, one for a word size of
three bits and the other for a word size of five bits.
This material was suggested by Guy Steele.

FIGURE 2. Plots of the least common multiple function LCM(x, y).
In Figure 2, the vertical scales are compressed; the highest peaks in the left figure are
of height LCM(6, 7) = 42.
