They are: 1*4*25 = 100
168 = 2 * 2 * 2 * 3 * 7

The two numbers that multiply to get sixty-three and add up to zero are 7 and -7. This is because 7 × -9 = -63 and 7 + (-9) = -2. The correct pairs, however, are 9 and -9, which multiply to 63 (9 × -7 = -63) and add up to 0 (9 + -9 = 0).
There are no three prime numbers that multiply to exactly 100, as 100 can be factored into its prime components, which are 2 and 5. The prime factorization of 100 is (2^2 \times 5^2), meaning it only consists of the primes 2 and 5. Since prime numbers must be distinct and cannot be repeated in this context, it is impossible to find three prime numbers that multiply to 100.
No two (or more) composite numbers can multiply to 30.

The two numbers that multiply to -30 and add up to 13 are 15 and -2. When you multiply 15 and -2, you get -30, and when you add them together, you get 13.
215 + 216 + 217 + 218 = 866
