(Pronic number is the number which is the product of two consecutive integers) Examples: 12=3×4, 20=4×5, 42=6×7 Before getting into programming, let us first develop our understanding of Pronic numbers. Pronic numbers are also called oblong numbers, heteromecic numbers, or rectangular numbers. Examples of first few pronic numbers are: 0, 2, 6, 12, 20, 30, 42, 56, 72, 90, 110, 132, 156. Consider number 12 from examples given in the question above. Factors of number 12 are: 1,2,3,4,6,12 (total six numbers).
