Numbers whose product is 1?

In general since the multiplication identity is one, the only number that can be a factor of 1 and still get one as a product is another 1.

Alternatively, any base raised to the zero exponent can equal 1.

Examples: 1*1=1

x^0 *1

X^0 * x^0.

Additionally any fraction that when multiplied by another fraction will yield the same numerator as

denominator are also a form of one.

Ex: 2/1 * 1/2 = 2/2 =1
