The answer is 105
3 x 35 = 105 or 105/3 = 35, therefore, 105 is a multiple of 3 and
7 x 15 = 105 or 105/7 = 15, therefore, 105 is a multiple of 7 and
5 x 21 = 105 or 105/5 = 21, therefore, 105 is a multiple of 5 so,
therefore, 105 is a multiple of 3, 7 and 5.
I calculated 3x7x5 to find 105.
there is no positive number less than 105 that is a multiple of all three numbers. If a negative number were allowed, the answer would be negative infinity. I doubt if that would be expected to be the correct answer.

Those are all prime numbers. The lowest common multiple must be their product.

105, there is no other lesser value that could make all fractions similar.
