its a factor with two pairs of the same number
A square number has an odd number of factors, but a number with an odd number of factor pairs is nothing special.
40 has four factor pairs:40 = 1 x 4040 = 2 x 2040 = 4 x 1040 = 5 x 8
80 has 5 factor pairs.
Factors come in pairs. If you know one factor, divide it into the number. The answer will be another factor.
1x40, 2x20, 4x10, 5x8 are all the factor pairs of 40.
An infinite number. The factor pairs are (40,1)(20,2)(10,4)(8,5)
24 does.
