• gcd(A, B, C, ...)—Returns the greatest common divisor, which is the largest integer that evenly divides all the values in A, B, C, ...

• lcm(A, B, C, ...)—Returns the least common multiple, which is the smallest positive integer that is a multiple of all the values A, B, C, ...

• mod(x, y)—Returns the remainder on dividing x by y (x modulo y). The result has the same sign as x.

• A, B, C, ... are real, dimensionless integers or arrays whose elements are real, dimensionless integers.

• x and y are real scalars, and y ≠ 0.
