It is always because if you have an improper fraction, the larger number is always the numerator. To get a reciprocal, you flip the fraction so that the denominator is the numerator, and vice versa. If the numerator is always bigger, and you make it the denominator, it would be proper.

Answer:
74676.
Step-by-step explanation:
Lets try multiplying 127 by 294 ( 127 is a prime number):
127 * 294 = 37338.
37338 / 196 = 190.5
37338 * 2 = 74676  which will now be divisible by 196.
74676 will be divisible by 98, 49 and 7 (because they are factors of  196).
It is also divisible by 84 ( to give 889) and therefore by 42, 28, 21, 14, 12,  6, 4, 3 , 2 and 1 which are all factors of 84.
