WebSolution 1. Start with the smallest prime number that divides into 72, in this case 2. We can write 72 as: 72 = 2 x 36. Now find the smallest prime number that divides into 36. Again we can use 2, and write the 36 as 2 x 18, to give. 72 = 2 x 2 x 18. 18 also divides by 2 (18 = 2 x 9), so we have: 72 = 2 x 2 x 2 x 9. WebMar 11, 2024 · Hashing is a one-directional process. Thus, we can’t retrieve the original data from its hash. Hash functions are deterministic. Hence, when we pass the same input to the hash function, it always generates the same output hash code, e.g. SHA-1 hashes are 160 bits long. Uniformity – hashes should be distributed evenly across possible values. tps 2.0 infineon toshiba satellite
