WebJul 10, 2024 · W.l.o.g. we can assume that each prime number in the factorization has power $1$. Since each number is $\le 10^6$, it can have at most $7$ distinct prime divisors, since for the product of $8$ smallest primes: $2 \cdot 3 \cdot 5 \cdot 7 \cdot 11 \cdot 13 \cdot 17 \cdot 19 > 10^6$. Therefore, each number has at most $2^7$ distinct divisors.

WebThe prime numbers from 1 to 1000 can be listed if we find out the number of factors of each number. We know that a prime number is a number with only two factors, 1 and the number itself. For example, let us take the number 11 which has only two factors which are 1 and 11 itself. So, 11 is a prime number. Let us take another number 12.
