Therefore, any number between 1- 1987 that can be divisible by 2,7,71cannot be regarded as a molecule.

A 1988/2- 1=993 is divisible by 2.

A 1988/7- 1=283 is divisible by 7.

1988/7 1-1= 27 is divisible by 71.

A1988/14-1=141is divisible by 2 and 7.

Divided by 2 and 7 1 is1988/14-1=14.

Divided by 7 are 1988/497- 1=4 and 7 1.

Divided by 2, 7 and 7 1 is1988/994-1=1.

So the molecular number is1987-(993+283+27)+(141+14+4)-1= 842.

That is, there are 842 simplest true scores with the denominator of 1988.

The second question is the same as the first one.

72=36*2

The product of a number multiplied by 72 is a complete square, which can be written as 2 * n 2 n is a positive integer.

The root number (2006/2)=3 1.7, so the maximum value of n is 3 1.

Such a number is 3 1.
