6.7.6  Simplifying a pair of integers: simp2

The simp2 command reduces a fraction to lowest terms, where the fraction is given as a separate numerator and denominator. (See also Section 6.32.6.)

• simp2 takes one or two arguments:
  [a,b], a list of two integers or simply the two integers a,b.
• simp2([a,b]) or simp2(a,b) returns the integers after they have been divided by their greatest common divisor; i.e., the corresponding fraction will be in lowest terms.

Examples.

• Input:
  simp2(18,15)
  Output:

  ⎡ ⎣

  6,5

  ⎤ ⎦

• Input:
  simp2([42,12])
  Output:

  ⎡ ⎣

  7,2

  ⎤ ⎦
