lcm(+Number1, +Number2, -Result)

-Result is lcm(+Number1, +Number2)

Number1

Integer.

Number2

Integer.

Result

Output: integer.

Description

The Least Common Multiple operation is only defined on integer arguments.

This predicate can be used as a function in arithmetic expressions. In coroutining mode, if Number1 or Number2 are uninstantiated, the call is delayed until these variables are instantiated.

Modes and Determinism

• lcm(+, +, -) is det

Exceptions

(4) instantiation fault

Number1 or Number2 is not instantiated (non-coroutining mode only).

(5) type error

Number1 or Number2 is a number but not an integer.

(24) number expected

Number1 or Number2 is not of a numeric type.

Examples

Success:
    Result is lcm(9, 15).		 % gives Result = 45
    Result is lcm(-9, 15).		 % gives Result = 45
    X is lcm(2358352782,97895234896224). % gives X = 38478583260342225282528 

Error:
    Result is lcm(1.0, 2).         (Error 5).
