Problem
Determine the greatest common divisors of {4, 3},
{12, 6}, and {36, 9}.
u "iLcm" Function
Syntax: iLcm(Exp-1, Exp-2[, Exp-3...Exp-10)]
(Exp-1 through Exp-10 all are integers.)
iLcm(List-1, List-2[, List-3...List-10)]
(All elements of List-1 through List-10 are integers.)
Function:
• The first syntax above returns the least common multiple for two to ten integers.
• The second syntax returns, in list format, the least common multiple (LCM) for each of the elements in two to
ten lists. When the arguments are {
b
d
and for
and
.
Description:
• All of the lists must have the same number of elements.
• When using the "iLcm(List-1, List-2[, List-3...List-10)]" syntax, one (and only one) expression (Exp) can be
include as an argument in place of a list.
Problem
Determine the least common multiples of {4, 3},
{12, 6}, and {36, 9}.
u "iMod" Function
Syntax: iMod(Exp-1/List-1, Exp-2/List-2[)]
Function:
• This function divides one or more integers by one or more other integers and returns the remainder(s).
Description:
• Exp-1 and Exp-2, and all of the elements of List-1 and List-2 must be integers.
• You can use Exp for one argument and List for the other argument (Exp, List or List, Exp) if you want.
• If both arguments are lists, both lists must have the same number of elements.
