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

Any two numbers whose product is '1' are each others' reciprocals.

1 & 1

There are no two numbers whose product is 23 and whose sum is 10. 23 is a prime number, and the only numbers whose product is 23 are 23 and 1. A prime number can only be divided by itself and 1.

well let's see, 1x1=1 so one of the two numbers whose product is one. =========================== I think you are looking for the word "reciprocal."
