Question

Is 6 a factor of 81 yes or no

Answer 1

To test whether it's a factor:

-- Divide the big number by it.                  81 / 6  =  13.5 .

-- If the quotient is a whole number,
   then the small number is a factor
   of the big number.                                  13.5 is not a whole number.

-- If the quotient is not a whole number,
   then the small number is NOT a factor
   of the big number.                                        6 is NOT a factor of 81 .
