It will take four. 2 x 3 x 5 x 7
30x7=210 so the answer is 30
The GCF is 1. That means the LCM is the two numbers multiplied together, or 210.
There are infinitely many possible answers. For example (5, 6, 7) (5.1, 5.7973, 7.1027) (5.11, 5.7801, 7.1099) and so on.

2 x 3 x 5 x 7 = 210 and 7 + 11 + 89 + 103 = 210 The question did not state whether the four prime numbers were to be added, subtracted, multiplied, or combined by some other operation.
One number equal to 210 is 210 but I don't think any other number would be equal to 210 other than 210.
The prime factors of 210 are 2x3x5x7.
