There are () odd numbers between 100 and 200, () even numbers, and () multiples of 5. The ones of 3 can be divided by 3 and 5 at the same time How many can be divided by 3 and 5 at the same time

There are (50) odd numbers between 100 and 200, 50 even numbers, 21 multiples of 5, 33 multiples of 3, and (7) divisible by 3 and 5 at the same time

The number (2 ^ 72 - 1) can be divided by three integers between 500 and 600
It is required that there be a process, not a patchwork

2 ^ 72-1 = (2 ^ 36 + 1) * (2 ^ 18 + 1) (2 ^ 9 + 1) * (2 ^ 9-1) 2 ^ 9 + 1 = 513, 2 ^ 9-1 = 511, there are two, 2 ^ 18 + 1 = (2 ^ 12-2 ^ 6 + 1) * (2 ^ 6 + 1) 2 ^ 9 + 1 = (2 ^ 6-2 ^ 3 + 1) * (2 ^ 3 + 1) and (2 ^ 6 + 1) * (2 ^ 3 + 1) = 65 * 9 = 585, so the three integers are 511513585

Urgent! The number that can be divided by 2 and 3 at the same time is less than 100
